    OPINION NOT REPORTED
    MEMORANDUM OPINION
    BY JUDGE McCULLOUGH                                           FILED: April 21, 2021
    The Commonwealth of Pennsylvania, Executive Offices (Employer),
    petitions for review from the May 13, 2020 order of the Workers’ Compensation
    Appeal Board (Board), which affirmed the decision of a workers’ compensation judge
    (WCJ) to the extent that she granted the claim petition filed by Kimberly Rothwell
    (Claimant) and vacated the decision insofar as the WCJ awarded Claimant counsel fees
    for Employer’s unreasonable contest.1 The issues presented to this Court are whether
    an expert’s opinion is rendered legally incompetent when the expert opines that a
    claimant’s job duties either caused or aggravated a work-related injury, without
    1
    Claimant did not appeal the Board’s decision vacating the award of counsel fees in her favor,
    and the only issue before the Court is whether the WCJ erred in granting Claimant’s claim petition.
    specifically choosing one over the other, and whether the expert possessed a sufficient
    foundation from which to issue a competent opinion.
    Background
    The relevant factual and procedural history of this case are as follows.
    After Claimant informed Employer that she suffered a work-related injury, Employer
    issued a notice of compensation denial on September 11, 2017, indicating that the claim
    was denied due to insufficient evidence that the injury was causally related to
    Claimant’s employment. On October 27, 2017, Claimant filed a claim petition,
    alleging that on August 31, 2017, she sustained, inter alia, a work-related injury in the
    nature of a cervical disc herniation at the C6-7 level and/or an aggravation of
    preexisting degenerative disc disease. The matter was assigned to a WCJ, who
    convened a hearing. At the hearing, Claimant’s counsel indicated that Claimant was
    seeking wage loss benefits for a closed period, specifically from September 23, 2017,
    to March 6, 2018, and the parties proceeded to adduce testimonial and documentary
    evidence.
    During the hearing, Claimant testified that she was employed by the
    Pennsylvania Human Relations Commission in 2004, investigating discrimination
    complaints, and she spent approximately 90% of her time typing on a computer.
    Claimant stated that in October 2007, she was involved in a work-related motor vehicle
    accident and developed problems with her knee, upper head, and neck; as a result, she
    was out of work from October 2007 to April 2008 and later returned to full duty work
    around October 2008. (WCJ’s Findings of Fact (F.F.) No. 1a., g.)
    Claimant further testified that in August or November 2016, she began to
    experience pain and fatigue in her hands, palms, and wrists, pain in her left arm in the
    2
    area between the wrist and elbow, and tension and pain on the left side of her neck and
    both shoulders. According to Claimant, she had worked at an ergonomically correct
    workstation, and Employer moved her office in November 2016, which did not have
    the same workstation configuration. Then, in February 2017, Employer returned
    Claimant to her original office station; however, the office did not have all the
    components of the ergonomically correct workstation that it did previously. Claimant
    stated that, after she moved back to her original office station, she began to experience
    increased pain in her fingers, palms, wrists, and left arm and, also, pain and stiffness in
    her neck and shoulder. Claimant said that, due to her ailments, she was unable to do
    all of the typing and manual tasks that she was required to do as part of her job duties.
    Claimant testified that sometime between March and August 2017, she requested
    Employer to provide her with accommodations, presented Employer with light-duty
    restrictions from her doctors, and eventually reported a work-related injury to
    Employer on August 31, 2017. Claimant testified that she stopped working on
    September 11, 2017, because Employer did not accommodate any of her doctors’ light-
    duty restrictions and that she continued to experience, inter alia, pain and stiffness in
    her neck and shoulders. (F.F. No. 1b.-f.)
    In the course of her testimony, Claimant added that in September 2017,
    she visited WorkNet at the direction of Employer and obtained a physician’s order for
    light-duty restrictions on September 8, 2017. Claimant explained that she had also
    been seeing Dr. Beredjiklian for swelling in her ring fingers and he, too, recommended
    the light-duty restrictions that she was given at WorkNet. In addition, Dr. Beredjiklian
    recommended that Claimant use an adjustable keyboard tray and a wrist cushion,
    undergo physical therapy, and see Dr. Simon for her neck complaints. Claimant
    testified that she first saw Dr. Simon in September 2017 and was still under his care at
    3
    the time of the hearing. Claimant said that Dr. Simon performed an MRI of her neck
    region, ordered physical therapy for her neck, and prescribed Neurontin and Lidocaine
    patches. (F.F. No. 1g.-h.)
    In support of her claim petition, Claimant submitted into evidence an
    office note from WorkNet dated September 11, 2017, and authored by Brian Birkmire
    PA-C. According to the office note, Claimant visited WorkNet and was evaluated for
    bilateral shoulder and neck pain with bilateral hand numbness and tingling. While
    being treated at WorkNet, Claimant reported that she had a previous work-related
    injury in 2007, after which Employer provided her with a workstation that was
    ergonomically correct. When Employer temporarily relocated Claimant’s office in
    November 2016, Claimant did not have an ergonomically correct workstation, and she
    started to experience pain and discomfort when typing and handling paper. The
    physical examination notes indicated that Claimant had diffuse tenderness over the
    upper trapezius and paraspinals, the elbow joints, and along the mid wrist region, but
    displayed a full range of motion in each of these areas. The office note stated that
    Claimant was released to modified duty, to be seen again in a week. (F.F. No. 3.)
    Claimant also submitted a report from Jeremy Simon, M.D., dated May
    31, 2018. The WCJ summarized the contents of this report as follows:
    a.    Dr. Simon is a physician at the Rothman Institute. Dr.
    Simon is board certified in physical medicine and
    rehabilitation.
    b.     Dr. Simon first saw Claimant on August 18, 2017, for
    complaints of neck pain with radiation to the shoulders. She
    also reported numbness and tingling in both hands. She had
    previously seen a hand specialist. Physical examination
    findings revealed neck pain with the Spurling’s test, spasm
    in the cervical paraspinals, and pain with rotation of the neck
    to the left. Dr. Simon diagnosed [Claimant with] cervical
    4
    disc displacement and ordered an ergonomic workstation,
    physical therapy, and an EMG.
    c.     An EMG dated August 24, 2017, showed an ulnar
    lesion of the elbow, which was demyelinating.
    d.    Dr. Simon next saw Claimant on October 23, 2017,
    and she reported ongoing complaints. An MRI of the
    cervical spine dated October 4, 2017, showed a disc
    protrusion at C6-7. Physical examination findings and the
    diagnosis were unchanged.         Dr. Simon prescribed
    medications and physical therapy.
    e.     Dr. Simon next saw Claimant on December 11, 2017.
    Claimant continued to complain of neck, shoulder, and arm
    pain. The symptoms were worse with prolonged sitting and
    turning her head and better with rest. She was using
    Gabapentin and Lidocaine patches which helped. The
    [medical] plan was to continue with medication and therapy
    and [to] consider an epidural injection at the next visit.
    f.    Dr. Simon next saw Claimant on January 22, 2018,
    and she reported that therapy was helpful, but she continued
    to have neck and arm symptoms. Dr. Simon continued
    therapy and medication.
    g.     Dr. Simon last saw Claimant on May 11, 2018. She
    was back to work and having difficulty at her workstation
    which was aggravating her neck and arm pain. On [physical]
    examination, she had limited strength in her arms and limited
    range of motion of her neck . . . . Dr. Simon opined that
    Claimant’s work activities of moving at work caused or
    aggravated a C6-7 disc herniation. Dr. Simon recommended
    that Claimant avoid prolonged sitting and a larger work space
    as well as an ergonomic evaluation of the workstation. These
    restrictions were related to her work injury. Dr. Simon
    opined Claimant continues to need medical treatment and
    restrictions for the work injury.
    (F.F. No. 4) (emphasis added).
    5
    In rebuttal, Employer offered two reports by John Handal, M.D., dated
    February 13, 2018, and August 20, 2018, respectively. The WCJ summarized the
    contents of these reports as follows:
    a.    Dr. Handal is a board certified orthopedic surgeon.
    b.     Dr. Handal evaluated Claimant at Employer’s request
    on February 13, 2018. Claimant related her job duties as an
    investigator. She described that she had pain in her left wrist
    and left hand and paresthesias in the small and ring fingers,
    with elbow pain radiating to the left wrist. She also described
    neck pain radiating to both shoulders. Claimant related that
    the symptoms began 6 to 9 months before August 31, 2017.
    However, on August 31, 2017, she described that while
    reaching to answer the phone, her computer mouse slipped
    off the desk and she flipped her left hand from a pronated
    position to a supinated position to catch the mouse. She then
    began having pain in her left wrist and hand and paresthesias
    into the small and ring fingers, elbow pain radiating into the
    left wrist, neck pain radiating into both shoulder in the
    posterior arm and into the extensor mass of the left forearm
    along the radial aspect into the wrist on both sides and
    numbness into the small and ring fingers. She summarized
    the treatment and testing she had received.
    c.     Physical examination findings revealed a normal
    motor examination in the upper extremities, negative
    Phalen’s and normal reflexes. There was a negative
    Hoffman’s sign, negative Lhermitte sign, and negative
    Spurling’s sign, but the Spurling’s maneuver reproduced
    neck pain. Cervical spine range of motion was full. Tinel’s
    testing was negative and Phalen’s testing produced
    numbness in the small and ring fingers bilaterally.
    d.     Dr. Handal reviewed medical records in conjunction
    with his examination which are listed on pages 3 and 4 of his
    report.
    e.     Dr. Handal opined that Claimant did not have findings
    on examination which were consistent with ulnar neuropathy
    or an ulnar nerve lesion. The EMG reported a very mild ulnar
    6
    neuropathy, but there were no physical findings on
    examination consistent with an ulnar neuropathy. Claimant
    did not need any medical treatment and could perform her
    regular job without restrictions.
    f.    Dr. Handal did not review the MRI report of the
    cervical spine dated October 4, 2017, and reserved comment
    on the neck injury.
    g.     Dr. Handal issued an addendum report on August 20,
    2018. Dr. Handal reviewed additional records. Dr. Handal
    noted that the mechanism of injury which Claimant described
    where she flipped her hand from a pronated position to a
    supinated position would not cause ulnar neuritis at the
    elbow or a cervical spine problem. In addition, the physical
    examination findings revealed no evidence of cervical
    radiculopathy or ulnar neuritis. Claimant did not need any
    medical treatment and could perform her regular job without
    restrictions.
    (F.F. No. 5.)
    Given the evidence presented, the WCJ credited Claimant’s testimony that
    she sustained a work injury which rendered her disabled from September 23, 2017, to
    March 6, 2018. (F.F. No. 10.) The WCJ also found that the opinions of Dr. Simon
    were credible and that “Claimant sustained a work injury in the nature of a C6-7 disc
    herniation as the result of her job duties.” (F.F. No. 11.) To the extent the opinions of
    Dr. Simon and Dr. Handal conflicted, the WCJ accepted the former over the latter. Id.
    Based on these credibility determinations and findings, the WCJ concluded that
    Claimant sustained her burden of proving that she suffered a work-related injury,
    specifically “in the nature of a C6-7 disc herniation, which rendered her disabled from
    September 23, 2017, to March 6, 2018,” and the WCJ granted Claimant’s claim petition
    for this closed period. (WCJ’s Conclusion of Law (COL) No. 2.)2
    2
    The WCJ also found that Employer engaged in an unreasonable contest and awarded
    Claimant’s counsel attorney’s fees. However, the Board disagreed and vacated this portion of the
    (Footnote continued on next page…)
    7
    Employer then appealed to the Board. With respect to the WCJ’s decision
    to grant Claimant’s claim petition, Employer argued that the WCJ erred in finding the
    testimony of Dr. Simon to be credible because Dr. Simon opined that Claimant’s work
    activities either caused or aggravated a cervical disc herniation. In Employer’s view,
    Dr. Simon’s opinion was equivocal and, thus, incompetent evidence. In rejecting this
    contention, the Board noted that the WCJ had complete authority over questions of
    credibility, evidentiary weight, and conflicting medical evidence.3 The Board also
    explained that a work-related aggravation of a preexisting condition is an injury within
    the meaning of the Workers’ Compensation Act (Act).4 For these reasons, the Board
    concluded that Dr. Simon’s testimony was competent and, having been accepted as
    credible by the WCJ, established that Claimant sustained a compensable, work-related
    injury under the Act.
    Before the Board, Employer also asserted that Dr. Simon’s opinions were
    incompetent because he had no knowledge of Claimant’s medical history.
    Additionally, Employer contended that WCJ erred in finding that Claimant’s testimony
    was credible.       Again, emphasizing the exclusive authority of the WCJ in rendering
    credibility determinations and deciding the weight to be accorded to the evidence, the
    WCJ’s decision. As mentioned above, Claimant did not file a petition for review challenging the
    Board’s ruling on the attorney’s fees issue. See supra note 1.

    “The law is well established that the WCJ is the ultimate factfinder and has exclusive
    province over questions of credibility and evidentiary weight. The WCJ, therefore, is free to accept
    or reject, in whole or in part, the testimony of any witness, including medical witnesses.” Dixon v.
    Workers’ Compensation Appeal Board (Medrad, Inc.), 
    134 A.3d 518
    , 524 (Pa. Cmwlth. 2016)

    8
    Board found no merit in Employer’s assertions of error. Accordingly, the Board
    affirmed the WCJ’s decision to grant Claimant’s claim petition.
    Thereafter, Employer filed a petition for review with this Court.5
    Discussion
    Employer first contends that the WCJ erred in concluding that Claimant
    met her burden of proof on the claim petition because Dr. Simon’s expert opinion was
    legally incompetent, particularly his testimony that Claimant’s work activities either
    “caused or aggravated a C6-7 disc herniation.” (F.F. No. 4g) (emphasis added). Citing
    dictionary definitions of the word “or,” Employer asserts that Dr. Simon’s testimony
    was equivocal because the term “or,” based on its plain meaning, “acts as a choice
    between different things” or “as an approximation [of] doubt or uncertainty.”
    (Employer’s Br. at 26.) According to Employer, “Dr. Simon utilized ‘or’ because he
    was unable to opine within a reasonable degree of medical certainty that Claimant
    sustained a C6-7 disc herniation as a result of her work activities instead of an
    aggravation of a preexisting disc herniation at C6-7.” Id. Employer thus argues that
    Claimant did not submit into evidence an unequivocal medical opinion regarding the
    nature of her work injury and, accordingly, failed to sustain her burden of proof.
    Pursuant to section 301(a) of the Act, “[e]very employer shall be liable for
    compensation for [] injury to [an] employe . . . in the course of his employment.” 77
    P.S. §431 (emphasis added). According to section 301(c)(1) of the Act, “[t]he term[]
    ‘injury’ . . . shall be construed to mean an injury to an employe, regardless of his
    5
    Our scope of review is limited to determining whether constitutional rights have been
    violated, whether an error of law has been committed, or whether findings of fact are supported by
    substantial evidence. Anderson v. Workers’ Compensation Appeal Board (Penn Center for Rehab),
    
    15 A.3d 944
    , 947 n.1 (Pa. Cmwlth. 2010).
    9
    previous physical condition, . . . arising in the course of his employment and related
    thereto, and such disease or infection as naturally results from the injury or is
    aggravated . . . by the injury.” 77 P.S. §411 (emphasis added).
    Ultimately, these statutory sections, for purposes of determining whether
    a claimant is entitled to compensation under the Act, do not differentiate between a
    classical “injury”—i.e., one that manifests itself solely as a discrete medical condition
    that is dissociated from any other or underlying medical condition that a claimant may
    have—and an exacerbated “injury”—i.e., one that comes to fruition as a medical
    condition because it stems from or is otherwise related or connected to a preexisting
    medical condition or physical impairment of a claimant. Rather, the Act and our case
    law treat both types of injuries as compensable injuries on equal terms and footing and
    any distinction between the two is superficial. This is especially true where, as here,
    only one employer is liable and there is no claim for apportionment against another
    employer. See generally South Abington Township v. Workers’ Compensation Appeal
    Board (Becker & ITT Specialty Risk Services), 
    831 A.2d 175
    , 181-82 (Pa. Cmwlth.
    2003) (discussing the nature of and dissimilarities between an “aggravation” and a
    “recurrence” of an injury in situations where a claimant has worked for different
    employers (or one employer had different insurance carriers) and sustained two work-
    related injuries).
    To be sure, “[s]ection 301(c)(1) makes it clear that, in determining
    whether an employee has suffered a compensable injury, his previous condition is of
    no consequence” and “the job-related aggravation of a disease is a category of ‘injury’
    for compensation purposes.” Pawlosky v. Workmen’s Compensation Appeal Board,
    
    525 A.2d 1204
    , 1210 (Pa. 1987). Thus, “[i]t may now be said, generally, that an
    employer takes an employee as he comes,” and the aggravation of a preexisting
    10
    condition is compensable, “even if the underlying disease itself was not caused by a
    work-related injury.” Id. at 1209. Indeed, “[i]t is well settled in Pennsylvania that an
    ‘aggravation of a preexisting condition’ is deemed a new injury for purposes of
    workers’ compensation law, thus, rendering the employer’s current insurance carrier
    responsible for all medical and wage loss benefits arising from claimant’s new injury.”
    South Abington Township, 
    831 A.2d 175
    , 181 (Pa. Cmwlth. 2003); see David B. Torrey
    and Andrew E. Greenberg, 8 West’s Pennsylvania Practice, Workers’ Compensation
    Law and Practice §4:56 (3d ed. 2008).
    Further, “neither the Act nor our case law has ever attempted to allocate
    responsibility based upon relative contributions of separate injuries to a single disabling
    medical condition.” South Abington Township, 
    831 A.2d at 182
    . Consequently, “[i]n
    the case of an aggravation, the [current] employer bears the entire responsibility for the
    claimant’s recent loss of earning power despite the fact that both injuries materially
    contributed to his current physical condition.” 
    Id.
     Viewed in this light, it should not be
    surprising that this Court has declined to “delineate an ecumenical definition of injury”
    and has focused instead on whether the injury is related to the employment. Workmen’s
    Compensation Appeal Board v. Bernard S. Pincus Co., 
    357 A.2d 707
    , 708 (Pa.
    Cmwlth. 1976), aff’d, 
    88 A.2d 659
     (Pa. 1978).6

    Pursuant to section 301(c)(1) of the Act, “an employee’s injuries are compensable if they (1)
    arise in the course of employment and (2) are causally related thereto.” Amandeo v. Workers’
    Compensation Appeal Board (Conagra Foods), 
    37 A.3d 72
    , 75-76 n.4 (Pa. Cmwlth. 2012). “In a
    claim petition for compensation, the claimant has . . . the burden of establishing a causal relationship
    between a work-related incident and an alleged disability.” Rife v. Workers’ Compensation Appeal
    Board (Whitetail Ski Co.), 
    812 A.2d 750
    , 754 (Pa. Cmwlth. 2002). To show that an injury was related
    to employment, the claimant must demonstrate a causal connection between work and the injury, and
    unequivocal medical evidence is required where it is not obvious that an injury is causally related to
    the work incident. Povanda v. Workmen’s Compensation Appeal Board (Giant Eagle), 
    605 A.2d 478
    , 486 (Pa. Cmwlth. 1992). Stated otherwise, medical experts testifying to a causal connection
    between the injury and the claimant’s employment “must testify, not that the injury or condition might

    Here, in pertinent part, Dr. Simon’s report provided as follows:
    [O]n August 18, 2017, [Claimant’s] chief complaint to me at
    that time was neck pain for several weeks with radiation to
    the shoulders. She described numbness and tingling into
    both hands. . . . [Claimant] noted pain that was worse with
    activities, turning her head, leaning her head to the side,
    somewhat relieved with changing positions. She also related
    to me that she had had neck issues from a previous work
    injury . . . .
    [O]n October 23, 2017, [Claimant’s] chief complaint at that
    time was pain in the neck and shoulders and numbness in the
    hands. Her MRI demonstrated a disc protrusion at C6-C7.
    She had a positive Spurling sign on the right. My impression
    was cervical disc displacement . . . .
    It is my medical impression that [Claimant] did have a work-
    related injury to the neck. This occurred when she was
    moving at work in February [2017] and developed
    symptoms. The nature of it[, i.e., the injury] is either [a]
    caused or aggravated [] C6-C7 disc herniation.
    (Claimant’s Ex. No. 2.)
    “The question of whether expert medical testimony is unequivocal, and,
    thus, competent evidence to support factual determinations is a question of law subject
    to our review.” Amandeo v. Workers’ Compensation Appeal Board (Conagra Foods),
    
    37 A.3d 72
    , 80 (Pa. Cmwlth. 2012). “Taking a medical expert’s testimony as a whole,
    it will be found to be equivocal if it is based only upon possibilities, is vague, and leaves
    doubt.” 
    Id.
     As a general rule, expressions such as “probably,” “possibly,” or “maybe”
    are equivocal in nature.        See Bemis v. Workers’ Compensation Appeal Board
    (Perkiomen Grille Corp.), 
    35 A.3d 69
    , 72 (Pa. Cmwlth. 2011).
    have or possibly came from the assigned cause, but that in his professional opinion the result in
    question did come from the assigned cause.” Lewis v. Workmen’s Compensation Appeal Board

    498 A.2d 800
    , 802 (Pa. 1985).
    12
    At the same time, however, “it is not the law . . . that every utterance which
    escapes the lips of a medical witness on a medical subject, must be certain, positive,
    and without reservation, exception, or peradventure of a doubt.” Philadelphia College
    of Osteopathic Medicine v. Workmen’s Compensation Appeal Board (Lucas), 
    465 A.2d 132
    , 134-35 (Pa. Cmwlth. 1983). Instead, expert testimony will be deemed competent
    evidence “even if the medical witness admits to uncertainty, reservation, doubt or lack
    of information with respect to medical and scientific details.” Id. at 135. Succinctly,
    “the requirement that medical evidence be unequivocal cannot reasonably be viewed
    as a demand for perfect testimony from members of the medical profession.”
    Children’s Hospital of Philadelphia v. Workmen’s Compensation Appeal Board
    (Washington), 
    547 A.2d 870
    , 872 (Pa. Cmwlth. 1988). This is “because medical
    science is not capable of absolute certainty in all matters and some opinions must
    necessarily be judgmental.” Fessler v. Workmen’s Compensation Appeal Board
    (Nationwide Insurance Co.),

    , 426 (Pa. Cmwlth. 1984).
    Our decisions in Manitowoc Co., Inc. v. Workers’ Compensation Appeal
    Board (Cowan), 
    74 A.3d 1137
    , 1142 (Pa. Cmwlth. 2013), and Liveringhouse v.
    Workers’ Compensation Appeal Board (Adecco), 
    970 A.2d 508
     (Pa. Cmwlth. 2009),
    are instructive and provide guidance on the issue presented.
    In Manitowoc Co., Inc., a case involving expert testimony as to the causal
    relationship between the work activity and the injury, this Court held that the “mere
    offering of alternative analyses with respect to a work-related injury does not render
    the expert’s testimony equivocal.” 
    74 A.3d at 1142
    . There, the claimant filed a fatal
    claim petition, alleging that his father fell from a crane platform at work and later died
    as a result of the injuries he sustained from the fall. The claimant’s expert set forth
    four possible explanations regarding the connection between the father’s fall and his
    13
    death: “(1) the fall caused mid-brain hemorrhaging and death; (2) the fall caused a
    massive head injury, resulting in cardiac and respiratory arrest, anoxic brain injury, and
    death; (3) the fall caused a blood clot in the back of [the] [f]ather’s throat, impairing
    his ability to breath and causing anoxic brain injury and death; or (4) the fall caused
    closed-head trauma, mid-brain hemorrhaging, secondary anoxic brain injury, and
    death.” 
    Id.
     Nonetheless, “[u]nder each of these scenarios, [the expert’s] ultimate
    conclusion was that the fall and blunt-force head trauma caused [the] [f]ather’s death,”
    and the expert opined “that absent the head trauma, [the] [f]ather would still be alive.”
    
    Id.
    Before this Court, the employer in Manitowoc Co., Inc. argued that the
    expert’s testimony was equivocal and incompetent. We disagreed, and, in so doing,
    reasoned as follows:
    The [Board] correctly concluded that an expert’s mere
    offering of alternative analyses with respect to a work-related
    injury does not render the expert’s testimony equivocal. To
    be unequivocal, the expert need only state that in his or her
    professional opinion, the result in question came from the
    assigned cause. Expert testimony is competent even if the
    witness admits to uncertainty, doubt, reservation, or a lack of
    information with regard to certain medical details, as long as
    the witness does not recant the opinion first expressed. Here,
    despite his uncertainty about the exact chain of physiological
    events, [the expert] opined, at every stage of the litigation,
    that the fall and head trauma caused [the] [f]ather’s death.
    
    Id.
     (internal citations omitted).
    In Liveringhouse, a WCJ dismissed a claimant’s review petition seeking
    to add carpal tunnel syndrome as an acknowledged work injury. In that case, the
    claimant’s doctor testified that the claimant’s job duties caused her carpal tunnel;
    specifically, he opined that the repetitive stress activity of her job “would likely cause
    the carpal tunnel syndrome, or if she even had some preexisting condition that was not
    14
    symptomatic, would aggravate that to the extent that it would become symptomatic.”
    Id. at 511-12 (emphasis added).
    Although the claimant’s doctor submitted testimony that was disjunctive
    in nature when characterizing the claimant’s injury, this Court nonetheless concluded
    that it was competent and unequivocal. We explained:
    [The doctor’s] testimony viewed as a whole unequivocally
    indicates that [the] [c]laimant’s carpal tunnel syndrome was
    caused by her job duties. He testified that . . . the actual EMG
    numbers [were] conclusive for severe carpal tunnel on the
    right and moderate to severe carpal tunnel on the left. The
    WCJ chose to emphasize [the doctor’s] opinion that [the]
    [c]laimant’s job duties would ‘likely’ cause carpal tunnel, but
    [the doctor] also opined that even if she had some pre-
    existing condition that was not symptomatic her job duties
    would aggravate it to the extent that it would become
    symptomatic. A doctor’s testimony should be considered as
    a whole, and a determination of whether it is unequivocal
    should not rest upon a few words taken out of context.
    Id. at 515. In essence, our decision in Liveringhouse strongly suggests that an expert’s
    opinion will not be deemed incompetent simply because an expert testifies that a
    claimant’s work duties either caused an injury or aggravated a preexisting injury.
    Applying the legal principles discussed above, we conclude that the WCJ
    did not err in determining that the testimony of Dr. Simon, via his report, constituted
    competent evidence. Here, the WCJ found that “Claimant sustained a work injury in
    the nature of a C6-7 disc herniation as the result of her job duties.” (F.F. No. 11.)
    Although the WCJ credited and relied on the testimony of Dr. Simon in reaching this
    conclusion, and Dr. Simon stated that Claimant’s C6-7 disc herniation was caused by
    her work duties or that her work duties aggravated a preexisting injury and caused a
    C6-7 disc herniation, the net result is the same—that is, either way, Claimant sustained
    15
    a work injury in the nature of a C6-7 disc herniation. Notably, Claimant had a history
    of problems with her neck: she had been involved in a work-related motor vehicle
    accident in October 2007 and experienced pain in her neck region from that moment
    onward, intermittently and increasingly, up until she reported the present work-related
    injury to Employer in August 2017.          Given Claimant’s medical history, it is
    understandable that Dr. Simon could not be absolutely certain, from a scientific
    standpoint, whether Claimant’s injury was an aggravation of a preexisting injury or a
    distinct injury in its own right, for “some opinions must necessarily be judgmental.”
    Fessler, 484 A.2d at 426.
    Moreover, as explained previously, the statutory and case law establish
    that a work-related aggravation to a preexisting injury is compensable to the same
    extent and manner as a work-related injury that manifests itself discretely. While it
    may be presumed that an expert’s testimony could be equivocal with regard to the
    characterization of the nature of the injury, that is not the case here. In other words,
    Dr. Simon did not testify that it was “possible” or “somewhat likely” that Claimant
    suffered a C6-7 disc herniation because her work duties caused the injury or aggravated
    a preexisting condition that resulted in the injury. To the contrary, the testimony of Dr.
    Simon, akin to the doctors’ testimony in Manitowoc Co., Inc. and Liveringhouse,
    unequivocally, unconditionally, and unambiguously demonstrated that Claimant’s
    injury was caused by her work duties. And, analogous to the doctors’ testimony in
    Manitowoc Co., Inc. and Liveringhouse, Dr. Simon rendered his expert opinion based
    on alternative theories. However, as in Manitowoc Co., Inc. and Liveringhouse, this
    fact, standing alone, does not render his opinion incompetent. Therefore, we find no
    merit in Employer’s contention.
    16
    Somewhat relatedly, Employer contends that Claimant failed to present
    unequivocal medical evidence establishing a causal connection between a C6-7 disc
    herniation and her work duties. More specifically, Employer asserts that Dr. Simon’s
    opinion was equivocal in this regard because he vaguely stated that Claimant’s injury
    “occurred when she was moving at work in February [2017] and developed
    symptoms.” (Claimant’s Ex. No. 2.)
    However, it is well settled “that, for an injury to be compensable under
    the Act, it is not required that the injury have resulted from any sudden occurrence or
    accident; it may be due to daily trauma or to a daily aggravation of a preexisting injury.”
    SKF USA, Inc. v. Workers’ Compensation Appeal Board (Smalls), 
    728 A.2d 385
    , 388
    (Pa. Cmwlth. 1999). Further, for an injury to be compensable, a claimant need not
    prove that she sustained an injury on “specific dates, and by specific events on those
    dates.” Sheetz v. Workmen’s Compensation Appeal Board (Firestone Tire & Rubber
    Co.), 
    522 A.2d 146
    , 152 (Pa. Cmwlth. 1987). Here, Claimant testified that
    [h]er symptoms worsened around February 2017 after the
    move from the temporary location to the remodeled office.
    She again had to pack and unpack, disassemble and move
    equipment, case files and personal belongings and she began
    to experience pain in her neck, shoulders and left forearm.
    When she returned to the permanent location, she no longer
    had an ergonomic workstation. Claimant’s symptoms
    continued to worsen between March and August 2017. The
    pain in her last two fingers, palms and wrists had worsened
    and she began to have pain in the left side of her neck and
    behind the shoulder blades. She was having difficulty
    carrying heavier case files, completing written reports,
    staying on the phone to complete extended interviews and
    maintaining case files in which each document had to be
    fastened and hole-punched into the file.
    (F.F. No. 1e.)
    17
    Notably, Claimant conveyed this information to Dr. Simon, and the WCJ
    found Claimant’s testimony to be credible. In forming an opinion, a medical expert
    may rely on the personal history given to him by the claimant, so long as the claimant’s
    testimony is competent and accepted as true by the factfinder. Somerset Welding &
    Steel v. Workmen's Compensation Appeal Board (Lee), 
    650 A.2d 114
    , 118 (Pa.
    Cmwlth. 1994). Simply put, Claimant suffered an injury in February 2017, and it
    continued to worsen through time, up to the point where Claimant could no longer work
    in August 2017. Given this record, we fail to discern how Dr. Simon’s testimony
    regarding the occurrence of Claimant’s injury was legally incompetent.
    Finally, Employer asserts that “Dr. Simon’s opinions are also incompetent
    because Dr. Simon had no knowledge of Claimant’s physical condition before he
    initially examined her on August 18, 2017, and did not review her extensive medical
    records before August 2017 documenting many years of complaints to her cervical
    spine and many years of medical treatment to said body part.” (Employer’s Br. at 29.)
    Employer further argues that Claimant did not provide Dr. Simon with a complete
    medical history and had separate accounts of when and to what extent she injured her
    neck in 2017 while working for Employer. In addition, Employer baldly contends that
    Dr. Simon had no reasonable basis to render an opinion.
    Pursuant to Pennsylvania law, an expert opinion is not competent to
    establish causation when “it is based upon a series of assumptions that lack a factual
    predicate.” City of Philadelphia v. Workers’ Compensation Appeal Board (Kriebel),
    
    29 A.3d 762
    , 770 (Pa. 2011). Somewhat similarly, where “an expert’s opinion is
    dependent upon information that is inaccurate or lacks support in the record, it is
    deemed incompetent.” Id. at 770 (internal citation and parenthetical omitted). At the
    same time, this Court has held that, when considering the evidentiary basis for an
    18
    expert’s opinion, a medical opinion is rendered incompetent only if it is based solely
    on inaccurate or false information. Degraw v. Workers’ Compensation Appeal Board
    (Redner's Warehouse Markets, Inc.), 
    926 A.2d 997
    , 1001 (Pa. Cmwlth. 2007);
    American Contracting Enterprises, Inc. v. Workers’ Compensation Appeal Board
    (Hurley), 
    789 A.2d 391
    , 396 (Pa. Cmwlth. 2001).
    Here, Employer does not cite to any information upon which Dr. Simon
    relied to formulate his expert opinion that was either false, inaccurate, or unsupported
    by the evidence of record. Notably, in a series of decisions, this Court has concluded
    that the fact that an expert does not have all of the claimant’s medical records, or fails
    to review them or the claimant’s job descriptions, or does not know all of the details of
    the mechanics of the claimant’s injury, are matters that go to the weight to be given to
    the expert’s testimony, not its competency. See, e.g., Degraw, 
    926 A.2d at 1001
    ;
    Samson Paper Co. & Fidelity Engraving v. Workers’ Compensation Appeal Board
    (Digiannantonio), 
    834 A.2d 1221
    , 1224 (Pa. Cmwlth. 2003); American Contracting
    Enterprises, 
    789 A.2d at 396
    . Similarly, allegations that an expert did not conduct
    enough physical examinations of a claimant or failed to order additional diagnostic
    testing are matters that pertain to the weight of the evidence, and not its competency.
    Berger v. Workers’ Compensation Appeal Board (Lehigh University) (Pa. Cmwlth.,
    No. 907 C.D. 2014, filed January 18, 2015) (unreported), slip op. at 13 n.4;7 Coyne v.
    Workers’ Compensation Appeal Board (Villanova University), 
    942 A.2d 939
    , 955 (Pa.
    Cmwlth. 2008); Workmen’s Compensation Appeal Board (Bethlehem Steel) v.
    Czepurnyj, 
    340 A.2d 915
    , 919 (Pa. Cmwlth. 1975).                    Consequently, Employer’s
    arguments are refuted by the case law and are devoid of merit.
    7
    We cite Berger, an unreported decision, for its persuasive value in accordance with section
    414(a) of the Commonwealth Court’s Internal Operating Procedures, 
    210 Pa. Code §69.414
    (a).
    19
    Therefore, having concluded that Employer has failed to present this
    Court with a meritorious argument establishing that the tribunals below committed
    error in their decisions, we affirm the Board’s order affirming the WCJ’s grant of
    Claimant’s claim petition.
