    ORDER
    This is an appeal from the Industrial Accident Board (“Board”). Employee-
    Appellant Jennifer L. Windle appeals the Board’s September 27, 2016 Decision
    denying Windle’s Petition to Determine Compensation Due,l Upon consideration
    of Windle’s appeal;2 Employer-Appellee the State of Delaware’s opposition
    thereto;3 and the record in this case, the Court hereby finds as follows:
    1. On February 17, 2015, Jennifer Windle suffered a compensable injury to
    the cervical spine While performing snow removal Work in the course of her
    employment as a custodian in the Christina school district. Her employer, the State

    Dccision"``) (Trans. 
    ID. 59751850). 2
    Employee-Appellant’s Opening Brief on Appeal of the Industrial Accident Board’s Decision
    Dated September 27, 2016 (“Windle Op. Br.”) (Trans. 
    ID. 60187719); Employee-Appellant’s
    Reply Brief on Appeal of the Industrial Accident Board’s Decision Dated September 27, 2016
    (Trans. 
    ID. 60324137). 3
    Answering Brief of Appellee, State of Delaware in Support of the Industrial Accident Board’s
    Decision of September 27, 2016 (Trans. 
    ID. 60268174). of
    Delaware, acknowledges that Windle suffered a compensable injury, but
    maintains that that injury Was a cervical strain that Was resolved by no later than
    November ll, 2015.4 Consequently, When Windle sought medical treatment
    expenses for a June 2016 cervical spine surgery and total disability benefits, the
    State refused on the basis that the compensation sought is not causally related to
    the February 17, 2015 Work accident.
    2. On April 22, 2016, Windle filed a Petition for Determination of
    Compensation Due, and on September 6, 2016, the Board held a hearing.5 The
    Board considered the testimony of: (1) Dr. James Zaslavsky, an orthopedic
    surgeon, who proposed the June 2, 2016 cervical spine surgery and opined that it is
    causally related to the February 17, 2015 Work accident;6 (2) Windle; and (3) Dr.
    Stephen Feddcr, a ncurosurgeon, Who opined that any injury Windlc sustained
    from the February 17, 2015 Work accident Was resolved by no later than November
    11, 2015.7
    3. Windle’s medical history, Which Dr. Zaslavsky and Dr. Fedder addressed
    in their testimony, is as follows. In 2008, Dr. Eric Tamesis, a rheumatologist,
    ordered that Windle receive a cervical spine X-ray in response to complaints of

    neck pain.8 Dr. Fedder testified that the 2008 X-ray showed a normal cervical
    curve with minimal degenerative changes, if any.9
    4. Beginning in November 2009, Windle received treatment from her
    primary care physician, Dr. Hasan, relating to joint pain, knee pain, and low back
    pain.10
    5. On September 20, 2010, Dr. Hasan recorded that Windle had left
    l and at some point, Dr.
    shoulder pain traveling down into her elbow and arm,l
    Hasan recorded a diagnosis of left carpal tunnel syndrome and left ulnar
    neuropathy.12 Windle denied having any history of left aim symptoms and
    testified that Dr. Hasan’s records incorrectly indicate that she experienced left arm
    issues, rather than right arm issues.13
    6. In 2011, Dr. Hasan recorded complaints of neck pain.14 Dr. Hasan
    referred Windle to physical therapy, and Windle reported to Dr. Hasan that her

    back and neck pain remained unresolved despite twelve sessions of physical
    therapy.15 Dr. Hasan then ordered an MRI.16
    7. Dr. Zaslavsky testified that the 2011 MRI showed moderate disk
    osteophyte complex at C4-5, with C5-6 appearing normal.17 Dr. Fedder testified
    that the 2011 MRI showed a mild amount of mass effect in the front of the spinal
    8 Comparing the
    cord at C4-5, with C5-6 and C6-7 appearing unremarkable.l
    2011 MRI to the 2008 X-ray, Dr. Fedder testified that there was an interval
    increase in degenerative disease consistent with the natural history of degenerative
    disease of the spine.19
    8. In 2012, Dr. Witherell diagnosed Windle with cervical radiculopathy at
    C6-7 and provided windle with a eei~vieal injectien.z° windle testified that the
    cervical injection administered by Dr. Witherell helped her and that after receiving
    the injection she was fine.21
    9. In 2013, Windle sustained a work injury, injuring her neck and low
    back.22 In response to that accident, Windle went to physical therapy.23 From

    sometime in 2013 through at least July ll, 2014, Dr. Hasan treated Windle for
    neck pain,24
    10. On February 17, 2015, Windle was injured while performing snow
    removal duties, which included lifting a snow shovel and raising and lowering a
    tractor plow with a lever.25 Windle testified that her job was very physical, and she
    worked full duty up until the accident.26 Following the accident, Windle sought
    care from Dr. Hasan. Windle reported neck pain, shoulder pain, left arm pain, and
    left hand pain.27 Dr. Hasan provided Windle with prescriptions for gabapentin and
    Flexeril.28
    ll. On March 6, 2015, Windle presented to one of Dr. Zaslavsky’s partners
    at First State Orthopaedics, Dr. Ginsberg.29 Windle relayed to Dr. Ginsberg that
    she continued to work full time but was struggling.30 Dr. Ginsberg recorded
    Windle’s complaints of left-sided neck pain radiating into the scapular region, right
    trapezius region, left triceps muscle, left hand, and fifth and fourth fingers.31 Dr.
    Ginsberg also documented a negative Spurling’s test and decreased sensation over

    C6 and C7.32 On physical exam, Dr. Ginsberg found evidence of decreased
    sensation and some weakness in Windle’s left arm.33
    12. With regard to Windle’s first meeting with Dr. Ginsberg, Dr. Zaslavsky
    testified that while Windle had a history of cervical complaints, she did not have a
    documented history of grip weakness or shooting pains down the arm related to the
    cervical spine.34 Dr. Fedder noted that, while Dr. Ginsberg described pain in the
    left neck and weakness in the left hand that indicate C7 radiculopathy, Dr.
    Ginsberg also recorded complaints of pain in Windle’s fourth and fifth fingers that
    indicate C8 or ulnar nerve pathology.35
    13. Following Windle’s March 6, 2015 appointment with Dr. Ginsberg, she
    attended physical therapy, but on April 15, 2015, Windle continued to report
    pain.36 Dr. Ginsberg scheduled a C7 selective nerve root block and asked Windle
    to follow up with Dr. Zaslavsky.37 On April 20, 2015, Dr. Ginsberg placed an
    injection on Windle’s C7 nerve root, which did not resolve Windle’s pain.38
    14. During this time, Windle underwent an MRI. Dr. Zaslavsky testified
    that the 2015 MRI showed herniated discs at C5-6 and C6-7 with left-sided

    foraminal stenosis.39 Dr. Zaslavsky described the hemiation as compressing the
    spinal cord and the nerves leaving the spinal cord at the C5-6 level.40 Dr. Fedder
    testified that the 2015 MRI showed a two to three millimeter protrusion with mild
    stenosis at C4-5, a two millimeter protrusion at C5-6, and a disc bulge at C6-7
    “with a shallow, left-sided foraminal two-three protrusion.”41 According to Dr.
    Fedder, while the C4-5 and C5-6 protrusions were trivial and clinically irrelevant,
    the changes from the 2011 MRI to the 2015 MRI were degenerative findings.42
    15. On May 6, 2015, Windle met with Dr. Zaslavsky. Among other things,
    Dr. Zaslavsky’s records describe grade 4 over 5 weakness of the left intrinsic
    muscles, wrist ilexors, and wrist extensors, as well as a positive Hoffman’s
    rellex.43 Dr. Fedder testified that the weakness as described, combined with the
    positive Hoffman’s reflex, may suggest myelopathy, but Windle’s MRI did not
    suggest the possibility or probability of myelopathy.44
    16. Dr. Zaslavsky recommended surgery, which Windle declined, so Dr.
    Zaslavsky told Windle to return if the pain became unbearable.45 Windle did not
    seek treatment from Dr. Zaslavsky again until March 2, 2016.46 In the interim,

    Windle continued to take pain medication, tramadol and gabapentin, and to work
    regular duty, but did not seek additional treatment for her work injury.47
    l7. In September 2015, Windle was diagnosed with seropositive rheumatoid
    arthritis (“M”), and thereafter, began treatment for RA with Dr. Hosny, a
    rheumatologist.48 In relation to Windle’s RA diagnosis, Dr. Fedder noted that Dr.
    Hosny regularly assessed diffuse cervical, thoracic, and lumbar spine complaints.49
    18. ln August, September, and November 2015, Windle saw Dr. Hasan, but
    Dr. Hasan did not document any arm weakness during those visits.50 In November
    2015, Dr. Hasan documented that Windle had a normal range of motion, normal
    muscle strength and tone, and unremarkable gait and station.51 Dr. Hasan
    described Windle’s neck as “supple,” and Windle denied tingling or numbness.52
    19. Windle testified that although her pain persisted following her February
    2015 work accident, her condition did not worsen until February 2016 when she
    began performing snow removal work again.53 Windle further testified that, in
    addition to unbearable pain, she was experiencing lack of grip strength and trouble
    turning her head left while driving.54

    20. Windle returned to see Dr. Zaslavsky on March 2, 2016.55 Dr.
    Zaslavsky testified that Windle reported a decline in her activities of everyday
    living, including worsening changes with fine motor activities, weakness of grip,
    and pain down her arrn.56 Although Dr. Zaslavsky’s March 2, 2016 notes indicate
    that Windle reported right arm pain, Dr. Zaslavsky testified this is a dictation error,
    and Windle’s predominant complaint remained left arm pain,57 Dr. Fedder
    testified that the medical records, which indicate left-sided weakness in 2015,
    right-sided weakness in March 2016, and left-sided weakness in April 2016,
    discount the possibility of a neurological finding in Windle’s case because
    neurological weakness cannot bounce from side to side.58
    21. Windle underwent another MRI on March lO, 2016.59 Dr. Zaslavsky
    testified that the 2016 MRI showed a worsening herniation at C5-6.60 Dr. Fedder
    testified that the 2016 MRI showed the pathologies at C4-5 and C6-7 improved
    compared to the 2015 MRI, but C5-6 worsened.61
    22. On April 20, 2016, Windle returned to Dr. Zaslavsky, and Dr. Zaslavsky
    disabled her from any and all employment as of that date.62 Dr. Zaslavsky

    recorded a left-sided Hoffman’s sign, disturbance in Windle’s balance, and
    weakness in her left side.63 Dr. Zaslavsky recommended addressing Windle’s
    condition with surgical treatment, and on April 22, 2016, Windle filed a Petition
    for Determination of Compensation Due.
    23. On June 2, 2016, Windle underwent surgery, consisting of an anterior
    cervical discectomy and fusion at C4-5 and C5-6.64 Windle testified that the
    surgery helped alleviate her symptoms, except for her arm which still has “tingling
    and pain that goes down” into her fingers.65 Dr. Fedder noted that Windle
    described the same type of symptoms_left-sided symptoms with diffuse
    weakness-before and after surgery.66
    24. on Jnly 12, 2016, Dr. Fedder examined windle.67 Dr. Fedder reviewed
    Windle’s medical records and obtained a medical history from Windle.68 With
    regard to Windle’s self-reported medical history, Dr. Fedder testified that Windle
    told him that, prior to February 2015, she was treated for low back complaints.69
    Dr. Fedder felt that Windle’s report of low back complaints was inconsistent with
    63 Board Decision at 5; Dep. Dr. Zaslavsky at 30:1-10.
    64 Board Decision at 5. In Dr. Zaslavsky’s opinion, although the herniation at the C5_6 level
    caused the majority of Windle’s symptoms, it was necessary to incorporate C4-5 into the fusion
    to prevent further surgery, Board Decision at 5_6; Dep. Dr. Zaslavsky at 31:9_32:6.

    her medical records which indicate neck complaints and treatments related to the
    neck.70
    25. Based on the foregoing history, Dr. Zaslavsky testified that Windle had
    a herniation at the C5-6 level that was compressing her spinal cord and the nerves
    leaving the spinal cord at the C5-6 level.71 Dr. Zaslavsky explained that a typical
    presentation for a patient with this type of hemiation would be both radiculopathy
    and myelopathy.72 ln response to Dr. Fedder’s testimony, Dr. Zaslavsky explained
    that a sprain/strain injury does not lead to radicular problems and neurologic
    changes.73 Specifically, Dr. Zaslavsky pointed to Windle’s changes in grip
    strength, fine motor activity, and balance as inconsistent with a cervical
    sprain/strain.74
    26. Dr. Zaslavsky also testified that Windle’s symptoms fit the expected
    progression.75 According to Dr. Zaslavsky, compression of the spinal cord, called
    central canal stenosis, typically gets worse in a step-wise fashion, meaning a
    patient may experience a period of bearable symptoms, followed by progressive
    loss of function.76 For example, a patient with central canal stenosis may
    experience periodic numbness and pain in the arms, worsening to full-time

    11
    numbness and pain, worsening to loss of balance and weakness of grip.77 On this
    point, Dr. Zaslavsky admitted that a traumatic event is not the only cause of central
    canal stenosis; it can also be caused by degenerative disc disease.76 However, Dr.
    Zaslavsky opined that central canal stenosis would not progress in the course of a
    couple months, even in a patient with seropositive RA.79
    27. In Dr. Zaslavsky’s opinion, the cervical spine surgery was reasonable,
    necessary, and related to Windle’s work injury.60 While the surgery helped resolve
    some of Windle’s symptoms, including balance and fine motor activities, Windle
    continues to have shooting pains in her left arm.61 Dr. Zaslavsky testified that the
    C6-7 level trying to compensate for the fusion above it may be causing Windle’s
    ongoing pain.62
    28. Contrary to Dr. Zaslavsky’s opinion, Dr. Fedder opined that Windle’s
    MRls reveal the natural history of a degenerative disease of the spine and do not
    evidence any kind of traumatic anatomic injury to the cervical spine.63 In support
    of his opinion that the MRls demonstrate a “lack of linkage” between the MRI
    findings and Windle’s clinical exams, Dr. Fedder specifically noted that although
    Dr. Zaslavsky’s records indicate intrinsic muscle weakness in Windle’s hand,

    intrinsic muscles are innervated by the C8 and Tl roots, and the MRls did not
    reveal any significant pathology in the C7-Tl area.64 Further, Dr. Fedder denied
    that the February 2015 work accident aggravated any pre-existing degenerative
    process in Windle’s cervical spine.85
    29. With regard to his opinion that Windle’s injury was resolved by
    November ll, 2015, Dr. Fedder testified that because Dr. Hasan’s November ll,
    2015 records describe a normal range of motion, unremarkable gait and station,
    and a “supple” neck, Windle “basically ha[d] a negative neurological inventory,”
    in his opinion.66 Thus, November 11, 2015 presented a logical end point for a
    cervical sprain/strain.67
    30. Dr. Fedder also testified that Dr. Zaslavsky’s medical records, which
    describe left-sided weakness, followed by right-sided weakness, and then left-sided
    weakness, do not support a finding of a spinal or neurological basis for Windle’s
    symptoms.66 However, Dr. Fedder clarified that he does not doubt Windle had
    legitimate pain complaints given that she has RA advanced enough to treat
    regularly with methotrexate.69

    31. By Decision dated September 27, 2016, the Board found that Windle
    had not met her burden of proof to show that her cervical spine condition, after
    November 2015, relates back to the February 17, 2015 work accident.96 ln
    reaching this decision, the Board found Dr. Fedder’s opinion very convincing.91
    The Board specifically enumerated four parts of Dr. Fedder’s testimony it found
    persuasive: (1) Dr. Fedder’s testimony regarding the timeline of Windle’s injury
    established by Dr. Hasan’s records, including Dr. Hasan’s November 2015 exam;
    (2) Dr. Fedder’s opinion that Windle’s current complaints of pain comport with her
    September 2015 seropositive RA diagnosis; (3) Dr. Fedder’s opinion that the
    diagnostic studies reflect a natural progression of a degenerative condition as
    opposed to traumatic work injury; and (4) Dr. Fedder’s opinion that Windle’s pain
    complaints are not neurologically based.92 In light of the foregoing, the Board was
    persuaded by Dr. Fedder’s opinion that by November ll, 2015, Windle’s February
    2015 cervical injury was resolved, and consequently, the Board found that any
    treatment Windle received after November 11, 2015, including the June 2, 2016
    cervical spine surgery, is causally unrelated to the compensable injury.93
    32. Windle argues: (1) the Board’s decision was not based on substantial
    evidence; and (2) the Board abused its discretion and erred as a matter of law by
    96 Board Decision at 20.

    allowing the State to question Windle about her personnel file and by admitting
    into evidence a statement related to a work incident.94
    33. On an appeal from the lndustrial Accident Board, this Court’s review is
    limited to determining whether the decision is supported by substantial evidence
    and free from legal error.95 Substantial evidence “means such relevant evidence as
    a reasonable mind might accept as adequate to support a conclusion.”96 This Court
    “does not sit as a trier of fact with authority to weigh the evidence, determine
    questions of credibility, and make its own factual findings and conclusions.”97
    Questions of law are reviewed de novo, but absent an error of law, the standard of
    review is abuse of discretion.96
    34. In support of her argument that the Board’s decision is not supported by
    substantial evidence, Windle points to Dr. Fedder’s lack of testimony accounting
    for Windle’s reported weakness in grip, balance issues, and shooting pain down
    her left arm.99 In contrast, Windle notes Dr. Zaslavsky’s testimony that the type of
    radicular pain/neurological symptoms Windle reported are consistent with Dr.
    Zaslavsky’s opinion that the work accident caused a disc herniation with spinal

    regarding the superiority of Dr. Zaslavsky’s opinion to Dr. Fedder’s opinion
    amount to a request that the Court “parse the experts’ testimony in order to reach
    its own decision about which expert is more convincing.”163 This the Court cannot
    do. The Board found that Windle suffered a cervical sprain/strain that resolved by
    November 11, 2015. In reaching this conclusion, the Board plainly stated that it
    found Dr. Fedder’s opinion very convincing, and the Board identified evidence to
    support the conclusion that Windle suffered a cervical sprain/strain, including: (1)
    Dr. Hasan’s November 2015 physical examination of Windle; (2) Dr. Fedder’s
    testimony that Dr. Hasan’s examination indicates that Windle had a negative
    neurological inventory at that time; (3) Windle’s seropositive RA diagnosis as a

    source of Windle’s complaints of pain; (4) Dr. Fedder’s testimony that Windle’s
    MRIs are consistent with the natural progression of a degenerative condition; (5)
    the persistence of Windle’s symptoms despite surgery; and (6) Windle’s
    preexisting cervical complaints.l64 The Court finds that the evidence enumerated
    by the Board is relevant evidence that a reasonable mind might accept as adequate
    to support the Board’s conclusion, Therefore, the Court finds the Board’s decision
    is supported by substantial evidence.
    36. In support of her argument that the Board erred when it permitted the
    State to question Windle about May 2015, February 2016, and April 2016
    disciplinary incidents, Windle maintains that the incidents were irrelevant.l65
    During the hearing, Windle’s counsel objected to the State’s questioning on the
    basis of relevance; the State argued that the disciplinary actions were relevant to
    Windle’s credibility regarding her symptomatology; and the Board permitted the
    questioning.l66
    37. In its decision, the Board recounted Windle’s testimony and its
    determination that the line of questioning about the disciplinary incidents was
    relevant to the credibility of her complaints in its summary of the evidence,l67 but

    the Board did not cite the line of questioning in its findings of fact and conclusions
    of law. Rather, the Board expressed concern over Windle’s credibility based on
    discrepancies between Windle’s testimony regarding her medical history and her
    medical records. The Board specifically noted: (1) Windle’s denial that she ever
    saw a rheumatologist prior to seeing Dr. Hosny when her medical records indicate
    she consulted with Dr. Tamesis in response to neck issues in 2008; and (2) her
    claim that Dr. Hasan treated her for right arm issues in 2010 when Dr. Hasan’s
    records consistently indicate that the treatment was for left arm issues.l66 The
    precise connection between the credibility of Windle’s complaints and her
    disciplinary record is not clear from the record; however, any error made by the
    Board on this issue is harmless. The core of the Board’s decision concerned the

    Windle’s credibility, it plainly enumerated discrepancies between her testimony
    and her medical records as the basis for its concerns regarding her credibility.
