    OPINION NOT REPORTED
    MEMORANDUM OPINION
    BY JUDGE FIZZANO CANNON                          FILED: February 28, 2022
    Geisinger Wyoming Valley Medical Center (Employer) petitions for
    review of the March 30, 2021 order of the Workers’ Compensation Appeal Board
    (Board) affirming the decision of the Workers’ Compensation Judge (WCJ) granting
    Claimant’s claim petition. Upon review, we affirm.
    I. Background
    Claimant works for Employer as an x-ray technologist.                WCJ’s
    Decision, 3/5/20 at 3, Finding of Fact (F.F.) 8, Reproduced Record (R.R.) at 97a.
    1
    This matter was assigned to the panel before January 3, 2022, when President Judge
    Emerita Leavitt became a senior judge on the Court.
    On March 27, 2019, Claimant was assisting a patient to get off an x-ray table when
    the patient pulled on Claimant’s left arm, causing immediate pain in Claimant’s neck
    and down her left arm. Id. Claimant also experienced a sensation down her entire
    left arm and her left-hand fingers went numb. Id.; see also Transcript of Testimony
    (T.T.), 11/26/19 at 12, R.R. at 39a. Claimant worked alone and immediately notified
    her supervisor of the incident via e-mail. F.F. 8. Claimant presented to Employee
    Health Services (Employee Health) the following morning and was prescribed
    muscle relaxers and four weeks of physical therapy. Id.; see also T.T., 11/26/19 at
    13-14, R.R. at 40a-41a. Claimant continued to work, even though her condition did
    not improve. Id. Employee Health discharged Claimant on April 29, 2019. F.F. 8.
    Claimant was still experiencing extreme pain and began treatment with Dr. Ryan
    Ness for pain management. Id. Dr. Ness referred Claimant to Dr. Russell Strom, a
    neurosurgeon with Employer’s Department of Neurosurgery, for a surgical
    consultation. F.F. 8-9; see also T.T., 11/26/19 at 19, R.R. at 46a. Claimant was
    prescribed another course of physical therapy by Dr. Akash Agarwal, Assistant
    Professor of Neurosurgery with the Milton S. Hershey Medical Center Department
    of Neurosurgery, in June 2019. F.F. 8 & 10. Both Dr. Agarwal and Dr. Strom
    recommended that Claimant undergo neck surgery. F.F. 8.
    Employer initially accepted a work-related injury in the form of “left
    shoulder/neck strains” in connection with the March 27, 2019 work incident. See
    Notice of Temporary Compensation Payable dated April 23, 2019, R.R. at 1a; see
    2
    also F.F. 2.2      Employer, Arch Indemnity Insurance Company and Esis, Inc.3
    (collectively, Respondents) halted the payment of benefits as of May 1, 2019 by
    means of a notice stopping temporary compensation and a notice of workers’
    compensation denial on the basis that Claimant did not sustain a work-related injury.
    F.F. 3. In May 2019, Claimant filed a claim petition alleging that she sustained a
    work-related injury on March 27, 2019 in the form of a cervical disc herniation4 as
    well as left shoulder, left arm and left thumb numbness. F.F. 5. The claim petition
    described Claimant’s work-related injuries as “injury to neck including but not
    limited to cervical disc herniation,” along with “[l]eft shoulder injury,” “[l]eft arm
    injury,” and “[l]eft thumb numbness,” further specifying that “Claimant may have
    other injuries which are not yet known[.]”                 Claim Petition at 2, R.R. at 8a.
    Respondents filed a timely answer to Claimant’s claim petition, denying the material
    allegations. F.F. 6.
    Claimant submitted a report based on an evaluation conducted by Dr.
    Strom on May 23, 2019. F.F. 9. Dr. Strom noted that he was treating Claimant on
    2
    The Notice of Temporary Compensation Payable specifically described the “nature of
    injury” as “Strain or Tear (Internal derangement, the trauma to the muscle or the musculotendinous
    unit from violent contraction or excessive forcible stretch)” with “no tears,” and noted that it
    occurred when a “[patient] pulled herself up using employee[’]s arm.” See R.R. at 1a.

    Arch Indemnity Insurance Company was identified as Employer’s insurer and Esis, Inc.
    was identified as Employer’s third-party administrator. See Notice Stopping Temporary
    Compensation at 1, R.R. at 3a; Notice of Workers’ Compensation Denial at 1, R.R. at 5a.

    The cervical spine contains six intervertebral discs, which are situated between adjacent
    vertebrae (one above and one below). See Cervical Herniated Disc Symptoms and Treatment

    referral from Dr. Michael James Grasso5 for neck pain radiating to the left thumb

    tendency to drop objects.               Id.; see also Dr. Auerbach Independent Medical
    Examination (IME) at 1, R.R. at 93a. Dr. Strom concluded that the magnetic
    resonance imaging (MRI) study revealed a disc herniation at C5-C6 causing severe
    cord compression, and that these findings correlated with Claimant’s complaints.
    F.F. 9; see also Dr. Strom Report at 8, R.R. at 78a. Further, Dr. Strom explained
    that the weakness in Claimant’s left hand was consistent with early cervical
    spondylotic myelopathy6 from cord compression, which usually results in
    progressive neurologic decline. Id.; see also Dr. Strom Report at 8-9, R.R. at 78a-
    79a. Dr. Strom recommended surgical intervention. F.F. 9.
    Claimant also submitted a report from Dr. Agarwal dated June 12, 2019
    following his examination of Claimant. See Dr. Agarwal Outpatient Letter at 1, R.R.
    at 80a.         Dr. Agarwal noted that Claimant “describe[d] symptoms of cervical
    radiculopathy on the left as well as neck pain.” Id. at 2, R.R. at 81a; see also F.F.
    10. Dr. Agarwal further noted that Claimant’s MRI study demonstrated disc
    herniation and disc osteophyte complex eccentric7 causing neural foraminal

    Dr. Agarwal Outpatient Letter at 2, R.R. at 81a; see also F.F. 10.
    Employer submitted a report based on an IME of Claimant conducted
    by Dr. Joshua Auerbach, an orthopedic surgeon, on August 19, 2019. F.F. 11. Dr.
    Auerbach opined that Claimant had a longstanding history of complaints pertaining
    to her neck, which predated the March 27, 2019 work incident, and that Claimant
    had not been forthcoming regarding her medical history. Id. Dr. Auerbach further
    opined that Claimant had sustained a cervical strain and sprain but experienced no
    aggravation of any preexisting degenerative cervical disc disease. Id.
    Employer also submitted an addendum report from Dr. Auerbach dated
    November 12, 2019, based on his review of additional medical records of Claimant
    generated by orthopedic surgeon Dr. David Kolessar and Dr. Grasso. See Dr.
    Auerbach Addendum at 1, R.R. at 93a. Dr. Auerbach noted that his review of the
    records indicated that Claimant received treatment for isolated left-sided carpal
    tunnel syndrome prior to the March 27, 2019 work incident. Id. at 2, R.R. at 94a.
    Dr. Auerbach stated that his opinion remained unchanged, and that Claimant
    experienced a cervical strain and sprain in the setting of preexisting degenerative
    cervical disease. Id.

    The term “Neural foraminal narrowing,” also referred to as “neural foraminal stenosis,”
    refers to “compression of a spinal nerve as it leaves the spinal canal through the foramen (the
    opening between the vertebrae through which spinal nerve roots travel and exit to other parts of
    the body).”         Neural Foraminal Stenosis Definition, SPINE-HEALTH, available at
    https://www.spine-health.com/glossary/neural-foraminal-stenosis (last visited Feb. 25, 2022).
    Neural foraminal narrowing “may occur in either the lower back (lumbar spine) or the neck
    (cervical spine), and be caused by an osteophyte, a foraminal herniated disc, or collapse of the disc
    space.” Id.
    5
    Claimant testified that she underwent surgery to alleviate carpal tunnel
    syndrome in January 2019, from which she completely recovered in six weeks. She
    experienced no other problems with her left hand pre-dating the March 27, 2019
    work incident. F.F. 8; see also T.T., 11/26/19 at 19, R.R. at 46a.
    After falling down a set of steps in 2009, Claimant experienced muscle
    pain in the back of her neck which resolved in about 10 days. F.F. 8. Claimant had
    not been diagnosed with a herniated cervical disc prior to the March 27, 2019 work
    incident, nor had she previously experienced similar symptoms. Id. Claimant
    asserted that in addition to other inaccuracies,9 Dr. Grasso’s records erroneously
    indicated that she was treating with him for neck pain. Id.; see also T.T., 11/26/19
    at 17, 22, 35-36, R.R. at 44a, 49a, 62a-63a.
    Claimant has been able to perform her regular job duties, although she
    struggles to transfer heavier patients. F.F. 8. Claimant also experiences difficulty
    vacuuming, carrying her purse on her left shoulder, reading the newspaper, turning
    her head to the right, and sleeping. Id.10
    On March 5, 2020, the WCJ rendered a decision and order granting the
    claim petition. See WCJ’s Decision, 3/5/20 at 1-6, R.R. at 95a-100a. The WCJ

    Claimant further noted that Dr. Grasso’s records incorrectly identified her height and
    erroneously stated that she had an aneurism in a lower extremity and that her cerebral aneurism
    was non-ruptured. See T.T., 11/26/19 at 37, R.R. at 63a.
    10
    Claimant further testified that she has received medical care in the past for a ruptured
    brain aneurism, and that she treats with Dr. Ness for pain management necessitated by a prior
    lumbar spinal fusion and problems with her sacroiliac joints. F.F. 8.
    “The sacroiliac joint connects the hip bones (iliac crests) to the sacrum, the triangular bone
    between the lumbar spine and the tailbone (coccyx). The primary function of the sacroiliac joints
    is to absorb shock between the upper body and the pelvis and legs.” Sacroiliac Joint Dysfunction
    (SI Joint Pain), SPINE-HEALTH, available at https://www.spine-health.com/conditions/sacroiliac-

    6
    found Claimant’s testimony genuine and credible based on his observations of her
    bearing and demeanor at the hearing. F.F. 8. The WCJ reasoned that “Claimant’s
    credibility [was] further bolstered by the fact that [she] has continued to work despite
    her injuries.” Id. Thus, the WCJ “specifically accepted [Claimant’s testimony] as
    fact.” Id.
    The WCJ also pointed out that Dr. Strom and Dr. Agarwal noted a
    correlation between the findings in the MRI study and Claimant’s subjective
    presentation, and that both doctors agreed that Claimant’s work-related injury was
    the cause of her complaints. Id. Thus, even though Claimant had not missed any
    time from work due to her injuries, the WCJ concluded that Claimant met her burden
    of demonstrating that she suffered disc herniations at C4-C5 and C5-C6 as a result
    of a work-related injury sustained in the March 27, 2019 work incident. F.F. 13;
    Conclusion of Law (C.L.) 2.11
    The WCJ rejected Dr. Auerbach’s opinions as lacking credibility. F.F.
    12. The WCJ found Claimant’s factual testimony concerning her personal medical
    history more credible than the “inferences” made by Dr. Auerbach following his
    review of Claimant’s medical records. Id. Moreover, the WCJ reasoned that the
    qualifications of Dr. Strom and Dr. Agarwal as neurosurgeons were “more
    persuasive” than those of Dr. Auerbach as an orthopedic surgeon, given the nature
    of Claimant’s injuries. Id. The WCJ further reasoned that the opinions of Dr. Strom
    and Dr. Agarwal were consistent and supported by Claimant’s credible testimony,
    11
    In addition to granting Claimant’s claim petition, the WCJ ordered that Respondents
    shall be responsible for the payment of medical bills associated with treatment of Claimant’s work-
    related injury and also for reimbursement of Claimant’s reasonable litigation costs. WCJ’s
    Decision, 3/5/20 at 6, R.R. at 100a.
    7
    whereas the opinions of Dr. Auerbach were contradicted by those of Claimant’s
    doctors and were undermined by Claimant’s testimony. Id.
    Employer appealed to the Board, which affirmed the WCJ’s decision
    by opinion and order dated March 30, 2021. See Board’s Opinion and Order, 3/30/21
    at 1-9, R.R. at 108a-16a. The Board concluded that the WCJ did not err in
    determining that Claimant met her burden of establishing that she sustained a work-
    related injury, because the WCJ accepted her testimony regarding her work injury
    and the pain she felt immediately afterwards. Id. at 6, R.R. at 113a (citing Inglis
    House v. Workmen’s Comp. Appeal Bd. (Reedy), 
    634 A.2d 592
    , 597 (Pa. 1993);
    Morgan (Workmen’s Comp. Appeal Bd.) v. Giant Mkts., Inc., 
    397 A.2d 415
     (Pa.
    1979))f. The Board noted that Claimant’s credible testimony and the diagnosis of
    disc herniations at C4-C5 and C5-C6 rendered by Dr. Strom and Dr. Agarwal
    supported the WCJ’s decision. See id.12 Thus, the Board rejected Employer’s
    assertion that the WCJ’s decision lacked substantial and competent evidentiary
    support. 
    Id.
     The Board further noted the Pennsylvania Supreme Court’s holding
    that medical testimony is not required to establish the requisite causal connection
    where a claimant sustains an alleged work injury while engaging in an act requiring
    force or strain and experiences pain at the point of force or strain. 
    Id.
     (citing
    Morgan). Thus, the Board concluded that even without the additional medical
    evidence, Claimant’s credible testimony as to pain experienced in her neck and left
    arm, with associated numbness and tingling in her left arm and hand, immediately
    Employer notes that Dr. Strom’s diagnosis did not include a C4-C5 disc herniation. See
    12
    Employer’s Br. at 27. This observation appears to be correct. See Dr. Strom Report at 8, R.R. at
    78a.
    8
    following the March 27, 2019 work incident, alone sufficed to establish the requisite
    causal connection. Id. at 6-7, R.R. at 113a-14a.
    The Board acknowledged that an expert medical opinion rendered in
    the absence of a full understanding of the alleged work incident or the claimant’s
    medical situation may be deemed incompetent. Id. (citing Long v. Workers’ Comp.
    Appeal Bd. (Integrated Health Serv., Inc.), 
    852 A.2d 424
    , 428 (Pa. Cmwlth. 2004)).
    Further, the Board “acknowledge[d] that the WCJ’s finding that both Dr. Strom and
    Dr. Agarwal agree[d] that Claimant’s work-related injury was the cause of her
    complaints . . . [was] not clearly supported by [the Board’s] review of their reports.”
    
    Id.
     at 7 n.2, R.R. at 114a (citing F.F. 12).
    Nevertheless, the Board reasoned, “the mere fact that Dr. Strom did not
    specifically mention the work-related incident in his report [was] not enough to
    establish that he did not have a full understanding of Claimant’s situation and [to]
    find him incompetent.” Id. at 7, R.R. at 114a. The Board noted that its “review of
    Dr. Strom’s report reveal[ed] a detailed assessment and plan based upon Claimant’s
    presenting symptoms and previous treatments up until that point,” and that “Dr.
    Strom also reviewed radiographic imaging to support his diagnoses.” Id. Therefore,
    the Board rejected Employer’s contention that Dr. Strom’s opinion was not
    competent on the basis that he failed to opine regarding whether Claimant’s injuries
    were work-related. Id. at 7, R.R. at 114a.
    Further, the Board “reiterate[d] that a medical opinion establishing
    causation was not required in [the present] matter as the injury was obvious pursuant
    to Morgan.”13 Id. The Board concluded that both Dr. Strom’s failure to specifically
    13
    The chairman of the Board dissented on the basis that “[w]hile it [was] not beyond reason
    that Claimant sustained an injury, the medical evidence [did] not support [the] conclusory
    9
    mention a work injury and Dr. Agarwal’s failure to proffer an explicit opinion on
    causation were harmless errors in light of its determination that Claimant’s credible
    testimony sufficed to establish causation. Id. (citing Morgan).
    Employer petitioned this Court for review.14
    II. Issues
    Before this Court,15 Employer contends that the Board erred in relying
    on Morgan because Claimant’s alleged work injury in the form of disc herniations
    at C4-C5 and C5-C6 was not obvious. See id. at 25-32. Further, Employer maintains
    that Morgan is distinguishable from the present matter, because “[a]lthough pain is
    an excellent indication of [an] injury, pain, in and of itself, is simply insufficient . .
    . to [support] a diagnosis of disc herniations in the cervical spine.” Id. at 26. Thus,
    Employer asserts that Claimant failed to prove that she sustained a work-related
    injury in the form of disc herniations at C4-C5 and C5-C6 as a result of the March
    27, 2019 work incident simply by testifying to the pain she felt immediately
    following the incident. Id. at 26-27.
    determination of C4-[C]5; C5-[C]6 disc herniation.” Board’s Opinion and Order, 3/30/21 at 9,
    R.R. at 116a. The dissenting chairman thus reasoned that it was “plausible” Claimant sustained
    irritation with muscle spasm, further noting that osteophyte formation and narrowing is
    degenerative. Id.
    14
    In June 2021, Employer filed a petition for supersedeas, which this Court denied by order
    dated July 12, 2021. See Geisinger Wyo. Valley Med. Ctr. v. Drozda (Workers’ Comp. Appeal
    Bd.) (Pa. Cmwlth., No. 427 C.D. 2021, filed July 12, 2021).
    15
    This Court’s scope of review is limited to determining whether constitutional rights have
    been violated, whether an error of law was committed or whether any finding of fact necessary to
    support the decision is not supported by substantial evidence. Odd Fellow’s Home of Pa. v.
    Workmen’s Comp. Bd. of Appeal (Cook), 
    601 A.2d 465
    , 467 (Pa. Cmwlth. 1991) (citing Section
    704 of the Administrative Agency Law, 2 Pa.C.S. § 704).
    10
    Additionally, Employer asserts that the medical evidence proffered by
    Claimant fails to establish the requisite causal connection.              See id. at 24-26.
    Employer notes that Dr. Strom’s May 23, 2019 report contains no reference to any
    work-related injury. Id. at 24. Employer also points out that Dr. Strom identified
    only a C5-C6 disc herniation causing severe cord compression, omitting mention of
    a C4-C5 disc herniation and failing to opine regarding whether Claimant’s C5-C6
    disc herniation was caused by the March 27, 2019 incident. Id. at 27. Thus,
    Employer asserts that the WCJ’s finding that Dr. Strom agreed Claimant’s work
    injury was the cause of her complaints is “simply untrue[.]” Id. at 24-25 (citing F.F.
    12).
    Employer also maintains that although Dr. Agarwal confirmed in his
    June 14, 2019 letter16 that Claimant suffers from C4-C5 and C5-C6 disc herniations
    and osteophyte complexes, Dr. Agarwal nevertheless failed to specifically opine as
    to whether the March 27, 2019 work incident was the cause. Id. at 24-25 & 29.
    Thus, Employer asserts that the WCJ erred in finding that both Dr. Strom and Dr.
    Agarwal agreed that the March 27, 2019 work incident was the cause of Claimant’s
    injury in the form of disc herniations at C4-C5 and C5-C6. Id. at 25. Employer
    “concedes that expert medical evidence would not be required to establish a
    diagnosis of neck pain radiating down the left arm with numbness and tingling in the
    hand,” as such symptoms “would be [indicative of] an obvious injury[.]” Id. at 29-
    30. However, Employer notes that the WCJ identified Claimant’s work injury as
    C4-C5 and C5-C6 disc herniations and maintains that the causal relation to the
    March 27, 2019 work incident is not obvious, as it is not readily discernible by an
    16
    Employer presumably intends to reference Dr. Agarwal’s report dated June 12, 2019 and
    signed electronically on June 14, 2019. See Dr. Agarwal Outpatient Letter at 1, R.R. at 80a.
    11
    untrained layperson. See id. Thus, Employer maintains that the Board erred in
    affirming the WCJ’s determination on the basis that Claimant’s testimony alone
    sufficed to establish that she sustained a work-related injury in the form of disc
    herniations at C4-C5 and C5-C6. See id.
    Moreover, Employer contends that Claimant’s failure to seek medical
    treatment immediately following the March 27, 2019 incident and her ability to
    continue performing her regular job duties undermines her position. See id. at 31.
    Employer, therefore, maintains that Claimant’s testimony would “[a]t best” support
    a causal relationship between the March 27, 2019 work incident and a diagnosis of
    strain or contusion. Id. Thus, Employer requests that this Court reverse the Board’s
    March 30, 2021 order. Id. at 34.
    III. Discussion
    “In a workers’ compensation claim petition proceeding, the claimant
    has the burden of establishing the right to compensation and all of the elements
    necessary to support an award, i.e., an injury sustained in the course of employment
    and related thereto.” Giant Eagle, Inc. v. Workers’ Comp. Appeal Bd. (Thomas),
    
    725 A.2d 873
    , 876 (Pa. Cmwlth. 1999) (citing Inglis House, 
    634 A.2d 592
    ).
    “[U]nequivocal medical testimony is required to establish a causal connection
    between an accident and a disability [o]nly where the connection is not obvious.”
    Morgan, 397 A.2d at 416; see also Giant Eagle, Inc., 
    725 A.2d at 876
     (“What is
    required to establish this causal connection is dependent upon whether or not the
    injury is obviously work-related.”). “An obvious relationship exists where the
    claimant’s injuries immediately and directly or naturally and probably result from a
    work incident; in such cases, the fact finder is not required to depend alone, or at all,
    12
    upon medical testimony to find the causal connection.” Metelo v. Workmen’s Comp.
    Appeal Bd. (Old Original Bookbinders Rest.),

    1994) (emphasis omitted); cf. Whiteside v. Workmen’s Comp. Appeal Bd. (Unisys
    Corp.), 
    650 A.2d 1202
    , 1204-07 (Pa. Cmwlth. 1994) (“claimant was required to
    provide unequivocal medical testimony that her physical condition was caused by
    her work environment” where claimant testified that an increase in job-related stress
    caused various physical maladies and “there [was] no discrete incident to which the
    injury [could] be attributed”). This Court has explained:
    An obvious injury is one that immediately manifests itself
    while a claimant is in the act of doing the kind of work
    which can cause such an injury. A classic example would
    be the laborer who grabs his back in pain after lifting his
    shovel full of wet concrete. In such a case, the causal
    connection is so clear that a lay[]person can see the
    connection. Under such circumstances, the claimant’s
    testimony is sufficient to connect the injury to the
    claimant’s employment, and additional medical testimony
    is not required.

    Employer asserts that the Board erroneously relied on Morgan to
    conclude that Claimant established the requisite causal connection between the
    March 27, 2019 work incident and the cervical disc herniations simply by testifying
    to the pain she experienced immediately following the incident.17 See Employer’s
    17
    Employer’s fourth question presented reads as follows:
    Whether the [] Board committed an error of law in finding that []
    Claimant was not required to submit any unequivocal expert
    medical opinion evidence to establish that she sustained a work[-
    13
    Br. at 26-27. We disagree. In Morgan, the claimant injured his back while unloading
    items off of employer’s delivery truck. See Morgan, 397 A.2d at 415-16. The
    claimant testified that he immediately experienced “a lot of pain” and “a feeling of
    being paralyzed.” Id. He initially treated with “the company doctor,” who referred
    him to an orthopedic surgeon with whom he treated for approximately three months.
    Id. at 416. The claimant did not proffer any expert medical evidence. Id. at 415. He
    received a favorable workers’ compensation award, which this Court reversed. Id.
    On appeal, the Pennsylvania Supreme Court reversed this Court’s decision. Identif-
    ying the central issue as whether the facts as testified to by the claimant established
    the requisite causal connection between the work incident and the asserted injury,
    id., our Supreme Court held:
    The long-established rule is that unequivocal medical
    testimony is required to establish a causal connection
    between an accident and a disability [o]nly where the
    connection is not obvious. . . . Where one is doing an act
    that requires force or strain and pain is experienced at the
    point of force or strain, the injury may be found to have
    been established. Pain is an excellent symptom of an
    ]related injury and to establish causation between the work event
    and the diagnosis of disc herniations at C4-[C]5 and C5-[C]6.
    Employer’s Br. at 4. We note that to the extent this question could be construed as asserting that
    Claimant did not sustain any work injury, such a contention would be unavailing. The WCJ
    credited Claimant’s testimony that she experienced pain in her neck and down her left arm, a
    sensation down her left arm and numbness in her fingers immediately following the work incident.
    See F.F. 8. Further, Claimant treated with Employee Health the following morning. See F.F. 8;
    T.T., 11/26/19 at 13-14, R.R. at 40a-41a. Moreover, Dr. Auerbach opined on behalf of Employer
    that Claimant sustained a cervical strain/sprain. See F.F. 11; see also Dr. Auerbach IME at 7-8,
    R.R. at 90a-91a; Dr. Auerbach Addendum at 2, R.R. at 94a. Significantly, Employer in fact
    “concedes that pain at the time of the incident would support a finding of a sprain or strain at best.”
    Employer’s Br. at 26. Thus, we find that the Board did not err in affirming the WCJ’s
    determination that Claimant sustained a work-related injury. See C.L. 2; Board’s Opinion and
    Order, 3/30/21 at 6-7, R.R. at 113a-14a.

    injury. Of course, the trier of fact will determine the
    credibility of the witness’s testimony as to the total
    situation. We, therefore, find substantial competent
    evidence in the record to support the conclusion of the
    [Board] that the above facts establish a causal connection
    between the work incident and [claimant’s] injury.
    Id. at 416 (citations and quotation marks omitted).
    Here, the WCJ credited Claimant’s testimony that she experienced pain
    in her neck and down her left arm, a sensation down her left arm and left-hand
    numbness in her fingers immediately after the March 27, 2019 work incident. See
    F.F. 8; see also T.T., 11/26/19 at 12, R.R. at 39a. Like the injured employee in
    Morgan, Claimant was “doing an act that requires force or strain and pain [was]
    experienced at the point of force or strain[.]” Morgan, 397 A.2d at 416. As noted
    above, “[a]n obvious injury is one that immediately manifests itself while a claimant
    is in the act of doing the kind of work which can cause such an injury. . . . Under
    such circumstances, the claimant’s testimony is sufficient to connect the injury to
    the claimant’s employment, and additional medical testimony is not required.”
    Giant Eagle, Inc., 
    725 A.2d at 876
    ; see also Tobias v. Workmen’s Comp. Appeal Bd.
    (Nature’s Way Nursery, Inc.), 
    595 A.2d 781
    , 784-85 (Pa. Cmwlth. 1991) (noting that
    an “‘[o]bvious’ . . . connection between [an] injury and a disability” may “involve
    an immediacy of occurrence such as an immediate back injury following heavy
    lifting”); Davis v. Workmen’s Comp. Bd. of Appeal (United Parcel Serv.), 
    499 A.2d 703
    , 705 (Pa. Cmwlth. 1985) (“[T]here [could] be no doubt that unequivocal medical
    testimony [was] not required . . . to establish the relationship of [c]laimant’s
    disability to his employment . . . where the claim [was] for a back injury which
    immediately manifest[ed] itself while [c]laimant [was] in the act of doing the kind
    15
    of heavy work which can cause such an injury”; thus, “medical opinion testimony
    [was] not required.”).
    Moreover, this Court has specifically held that a claimant’s testimony
    regarding pain experienced immediately following a work incident may alone
    suffice to establish the requisite causal connection between the incident and an injury
    subsequently diagnosed as a disc herniation. See, e.g., Nw. Med. Ctr. v. Workers’
    Comp. Appeal Bd. (Cornmesser), 
    880 A.2d 753
    , 754-56 (Pa. Cmwlth. 2005)
    (testimony of claimant, a registered nurse, that he felt something pop in his back and
    experienced pain while moving a large patient at work established the requisite
    causal connection between the work incident and a work injury subsequently
    diagnosed as a herniated disc); Workmen’s Comp. Appeal Bd. v. Bethlehem Mines
    Corp., 
    349 A.2d 529
    , 530 (Pa. Cmwlth. 1975) (claimant’s testimony alone sufficed
    to establish that being pinned against a plank at work while attempting to remove a
    piece of a steel chute weighing several hundred pounds caused a lower back injury
    in the form of disc herniations, where claimant immediately complained of back pain
    following the work incident); Malecki v. Workers’ Comp. Appeal Bd. (Franklin
    Reg’l Sch. Dist.) (Pa. Cmwlth., No. 582 C.D. 2020, filed Mar. 26, 2021), slip op. at
    1-3, 9-13 (reversing the Board’s affirmance of the WCJ’s determination that
    claimant failed to establish a work-related injury, reasoning that claimant’s
    testimony that he experienced pain in his lower back and extending down the side
    of his left leg to his toes while lifting garbage into a dumpster established that
    claimant sustained a herniated disc as a result of the work incident); City of
    Allentown v. Workers’ Comp. Appeal Bd. (Porter) (Pa. Cmwlth., No. 1038 C.D.
    2011, filed Dec. 21, 2011), slip op. at 1-6 (claimant’s injury in the form of a herniated
    lumbar disc and radiculitis was obviously work related, where claimant testified that
    16
    he immediately experienced pain after pulling his back while lifting a heavy tool
    onto a truck at work).18
    Notably, the WCJ also credited Claimant’s testimony that she had no
    prior diagnosis involving herniated cervical discs and that she had not previously
    experienced similar symptoms. Cf. Sacks v. Workmen’s Comp. Appeal Bd., 
    402 A.2d 293
    , 294 (Pa. Cmwlth. 1979) (citing Morgan) (factfinder did not require
    medical testimony to find the requisite causal connection where claimant, a school
    bus driver for handicapped children, experienced severe pain in his right knee and
    foot immediately after lifting a 17-year-old boy onto a bus, noting that claimant had
    no prior history of back trouble, the pain began as soon as he lifted the child and the
    incident was reported immediately).
    We are unpersuaded by Employer’s assertion that Claimant’s purported
    delay in seeking medical care19 and her ability to continue performing her regular
    job duties undermine her position. See Odd Fellow’s Home of Pa. v. Workmen’s
    Comp. Appeal Bd. (Cook), 
    601 A.2d 465
    , 468-69 (Pa. Cmwlth. 1991) (noting
    employer’s contention that claimant “continued to perform her duties without
    complaint for four months before seeking medical attention” and holding, in relevant
    part, that “[a]lthough [claimant’s] [roughly four-month] delay in seeking medical
    care may have weakened the causal chain of events and raised the question of
    credibility, this did not preclude the referee from finding that [claimant] suffered a
    compensable injury,” noting that “[t]he [WCJ] found [claimant] to be credible, and
    18
    We cite these unreported opinions as persuasive authority pursuant to this Court’s
    Internal Operating Procedures. See 
    210 Pa. Code § 69.414
    (a).
    19
    We note Claimant’s testimony that the work incident occurred sometime around 5:30
    p.m. to 6:00 p.m. the evening of March 27, 2019 and that she sought medical attention the
    following morning. See F.F. 8; T.T., 11/26/19 at 13-14, R.R. at 40a-41a.

    from her testimony determined that the requisite relationship existed to establish a
    work-related injury”); Greene Cnty. Mem’l Hosp. v. Workmen’s Comp. Appeal Bd.
    (Cole), 
    432 A.2d 1166
    , 1167 (Pa. Cmwlth. 1981) (affirming grant of workers’
    compensation benefits and holding that “unequivocal medical testimony [was] not
    required” where claimant “alleged that she injured her back while lifting and turning
    a very heavy patient,” noting that while “[c]laimant continued to work for several
    weeks after the [work] incident, this [did] not preclude a finding that she suffered a
    compensable injury”).
    Moreover, here, the WCJ actually determined that “Claimant’s
    credibility [was] further bolstered by the fact that Claimant [] continued to work
    despite her injuries.” F.F. 8; see also Davis v. Workers’ Comp. Appeal Bd. (City of
    Phila.), 
    753 A.2d 905
    , 909 (Pa Cmwlth. 2000) (“In workers’ compensation cases,
    the WCJ is the ultimate fact-finder who must determine witness credibility and
    evidentiary weight. . . . The WCJ’s assessment of witness credibility is not subject
    to our review on appeal.”). We, therefore, agree with the Board that Claimant’s
    credible testimony concerning the pain and sensations she experienced immediately
    following the March 27, 2019 work incident sufficed to establish the causal relation
    between Claimant’s injury in the form of C4-C5 and C5-C6 disc herniations and the
    work incident. See, e.g., Giant Eagle, Inc., 
    725 A.2d at 876
    ; Morgan, 397 A.2d at
    415-16.20
    20
    Like the Board, we acknowledge Employer’s observation that neither Dr. Strom nor Dr.
    Agarwal specifically opined that the March 27, 2019 work incident was the cause of Claimant’s
    C4-C5 and C5-C6 disc herniations, and that Dr. Strom’s report does not reference any work-related
    injury. See Board’s Opinion and Order, 3/30/21 at 7 and 7 n.2, R.R. at 114a. Employer also points
    out that Dr. Strom’s diagnosis did not include a C4-C5 disc herniation. However, the WCJ found
    that “both Doctors [Strom and Agarwal] agree[d] that Claimant’s work-related injury was the
    cause of her complaints,” specifically describing Claimant’s compensable work-related injury
    18
    Employer asserts the following in its appellate brief:
    Dr. Agarwal confirm[ed] that the MRI of April 16, 2019
    reveals disc osteophyte complex at C4-[C]5 centered to
    the left causing moderate left neuroforaminal narrowing.
    He also confirmed that at C5-[C]6 there is moderate to
    severe central canal narrowing secondary to disc
    osteophyte complex and bilateral neuroforaminal
    narrowing. Dr. Agarwal [did] not specifically relate these
    findings to any work injury of March 27, 2019.          []
    Claimant’s testimony, in the absence of any unequivocal
    expert medical opinion evidence, cannot support [a] causal
    relationship between the March 27, 2019 event and the
    development of disc herniations and osteophyte
    complexes at C4-[C]5 and C5-[C]6.
    Employer’s Br. at 29. Employer further contends that “[d]isc herniations are not
    obvious injuries and can be present in the absence of any injury or trauma.” Id. at
    30. Nowhere in its appellate brief, however, does Employer specifically assert that
    any preexisting condition caused Claimant’s injury in the form of disc herniations at
    C4-C5 and C5-C6 prior to the March 27, 2019 work incident, or that Claimant’s
    injury resulted from the aggravation of any preexisting condition.21 Further, we note
    stemming from the March 27, 2019 work incident as “disc herniations at C4-[C]5 and C5-[C]6[.]”
    See F.F. 12; C.L. 3. To the extent the WCJ’s findings may be inconsistent with the medical reports
    submitted by Dr. Strom and Dr. Agarwal, we note that any such discrepancy constitutes harmless
    error in light of our disposition of this matter. See Sacks v. Workmen’s Comp. Appeal Bd. (Sacks),
    
    402 A.2d 293
    , 294 (Pa. Cmwlth. 1979) (citing Morgan) (affirming award of benefits even though
    claimant failed to present unequivocal medical testimony because “neither physician expressed
    any opinion on the relationship, if any, between claimant’s disability and the [work incident]
    incident,” where “claimant’s disability [was] immediately and directly the result of [the] work
    incident”).
    21
    We note that even if Employer had asserted that Claimant’s disc herniations resulted
    from the aggravation of a preexisting condition, Employer has cited no authority for its implicit
    argument that a claimant’s testimony alone cannot establish that a work incident caused
    “aggravation symptoms” where the causal connection is obvious. Cf. Knapp v. Workmen’s Comp.
    Appeal Bd. (GTE), 
    671 A.2d 258
    , 262 (Pa. Cmwlth. 1996) (“Of course, where there is no obvious
    19
    that the WCJ credited Claimant’s testimony regarding her medical history,
    specifically finding that “Claimant had never been diagnosed with a herniated
    cervical disc prior to her work-related injury and never previously experienced
    similar symptoms.” F.F. 8. Even though Dr. Agarwal noted that Claimant’s April
    16, 2019 MRI revealed a disc osteophyte complex causing neural foraminal
    narrowing at C4-C5 and C5-C6 of the cervical spine, the WCJ also credited
    Claimant’s testimony that she did not treat with Dr. Grasso for “neck complaints”
    prior to the work incident and that despite experiencing some muscle pain in the
    back of her neck after falling down a set of steps in 2009, that pain resolved in about
    10 days. See F.F. 8 & 10; Dr. Agarwal Report at 2, R.R. at 81a. Further, the WCJ
    credited Claimant’s testimony that she completely recovered within six weeks from
    her January 31, 2019 carpal tunnel surgery.                See F.F. 8.22       These credibility
    determinations and factual findings are binding on this Court. See A & J Builders,
    Inc. v. Workers’ Comp. Appeal Bd. (Verdi), 
    78 A.3d 1233
    , 1238, 1243 (Pa. Cmwlth.
    causal connection between the aggravation symptoms and the alleged work-related cause, that
    connection must be established by unequivocal medical evidence.”) (emphasis added); Somerset
    Welding & Steel v. Workmen’s Comp. Appeal Bd. (Lee), 
    650 A.2d 114
    , 117 (Pa. Cmwlth. 1994)
    (“In light of his previous back pain, an obvious causal connection does not exist between
    [c]laimant’s work-related incident and his injury.”) (emphasis added).
    22
    As summarized by Dr. Auerbach, a February 8, 2019 clinical note from Dr. Kolessar
    indicates that Claimant was pain-free following the January 31, 2019 carpal tunnel release. See
    Dr. Auerbach Addendum at 1, R.R. at 93a. Although Dr. Auerbach’s summary of Dr. Kolessar’s
    clinical note further indicates that Claimant experienced “[m]inor numbness in the fingertips,” this
    complaint presumably resolved by the time of the March 27, 2019 work incident, as the WCJ
    credited Claimant’s testimony that she achieved full recovery within six weeks of the carpal tunnel
    surgery. See F.F. 8.
    20
    2013) (“Unless made arbitrarily or capriciously, a WCJ’s credibility determinations
    will be upheld on appeal.”).23
    Accordingly, we affirm.

    We acknowledge that “the causal link is not obvious if a claimant has a pre-existing

    976 A.2d 597
