    United    Parcel    Service,     Inc.    (“UPS”)    and    Liberty    Mutual
    Insurance     Company    (collectively      “Defendants”)       appeal     from   an
    -2-
    Opinion and Award of the North Carolina Industrial Commission
    (“the Commission”) awarding Joel L. Cole, Jr. (“Plaintiff”) (1)
    temporary    total    disability       benefits    for    the     period   from   12
    December 2009 through 4 February 2010; (2) costs for medical
    treatment related to his injury from 11 December 2009 through 4
    February 2010; and (3) attorneys’ fees in the amount of 25% of
    Plaintiff’s    temporary       total    disability       award.       On   appeal,
    Defendants argue that the Commission erred in concluding that
    Plaintiff’s lower back condition was causally related to a work-
    related injury       suffered on 11 December 2009.                  After careful
    review, we affirm the Commission’s Opinion and Award.
    Factual Background
    At the time of the hearing, Plaintiff was 46 years old.
    Plaintiff    began    working   for     UPS   on   30    August    1985.     As   of
    December 2009, Plaintiff was a feeder driver.                   This job required
    him to drive tractor-trailers approximately 200 to 500 miles per
    day.    He was also required to lift up to 70 pounds of dolly1
    equipment and to assist in moving packages weighing up to 150
    pounds.
    On 11 December 2009, Plaintiff was working at UPS’s North
    Wilkesboro    Hub    Center.      His    supervisor,       LaShay    Cross   (“Mr.
    1
    A dolly is a piece of equipment used to couple two trailers
    together such that they can both be pulled by one tractor.
    -3-
    Cross”), instructed him to attach two trailers to a tractor and
    pull them to the Greensboro terminal.              While lifting a dolly in
    order to attach one of the trailers to his tractor, Plaintiff
    felt a sharp pain shoot from his left foot up to the back of his
    neck.      After a few minutes, the pain lessened and Plaintiff was
    able to continue working.         He called Mr. Cross to tell him that
    he had suffered an injury.        Plaintiff then drove from Wilkesboro
    to   the    Greensboro    terminal,     where   he    dropped   off   the    two
    trailers and picked up another trailer to haul to Winston-Salem.
    Upon arriving in Winston-Salem, Plaintiff called Mr. Cross a
    second time, asking if he could “check out” and go home because
    he was still in pain.        After completing his delivery, Plaintiff
    returned to his home at around 4:00 a.m.              By this time, the pain
    in his back had become so acute that he was having difficulty
    walking and “had to crawl in the house.”
    When    Plaintiff   awoke   later     that     morning,   his   pain   had
    worsened.      Plaintiff was transported to the emergency room at
    Forsyth     Medical   Center.      At    the    emergency   room,     Plaintiff
    “complained of back pain, radiating to the left leg, at a 10/10
    level of severity.”         Plaintiff was given pain medication and
    instructed to rest and stay out of work for four days.
    -4-
    On 17 December 2009, Plaintiff was examined by his primary
    care    physician,       Dr.   John    Galbreath      (“Dr.    Galbreath”).         Dr.
    Galbreath instructed Plaintiff to remain out of work and ordered
    a lumbar spine MRI scan.                The MRI scan showed abnormalities
    consistent with possible infection,                  significant swelling,          and
    severe facet joint degeneration at the L4 and L5 joints on the
    left side of his spine.             In light of these findings, Plaintiff
    was instructed to go to the hospital.
    On   18    December     2009,    Plaintiff     was     admitted     to   Forsyth
    Medical Center, where he came under the care of Dr. Arthur Link
    (“Dr. Link”), a specialist in infectious diseases.                         Dr. Link’s
    diagnosis        upon   admission      was    back   pain   secondary      to   lumbar
    abscess.         Plaintiff was given antibiotics intravenously by a
    peripherally inserted central catheter (“PICC”) line.                            During
    his hospitalization, Plaintiff developed pain in his left knee.
    His knee was aspirated, and gout crystals were found.
    On   24    December     2009,    Plaintiff     was     discharged    from   the
    hospital.        On 5 January 2010, Defendants sent Plaintiff to Dr.
    Shawn   Dalton-Bethea          (“Dr.   Dalton-Bethea”),        a    pain   management
    specialist,       for   a    one-time    evaluation.          Dr.   Dalton-Bethea’s
    impression was that Plaintiff’s condition was present before the
    -5-
    11 December 2009 incident and that his infection was not the
    result of the incident.
    Plaintiff continued to receive antibiotics via a PICC line
    administered         by    a     nurse      at    his     home.        On    6     January      2010,
    Plaintiff      was    seen        by    Dr.      David    Priest       (“Dr.       Priest”),      Dr.
    Link’s partner.                Dr. Priest completed a short-term disability
    claim   form     on       26    February         2010,    certifying         that      Plaintiff’s
    disability was “due to employment” and began on 12                                          December
    2009.     On 9 May 2011, Plaintiff was evaluated by Dr. Thomas
    Craig     Derian          (“Dr.        Derian”),         an    orthopedic             surgeon     who
    specializes in the lumbar spine and the treatment of infectious
    conditions       that          impact    the      spine.          Dr.       Derian        determined
    Plaintiff’s condition was “most consistent with underlying facet
    joint     degeneration            at     L4-5       and       L5-S1,        with      degenerative
    spondylolisthesis,              with    a     work-related        injury         on   11    December
    2009,   likely        resulting          in      inflammation      in       that      area,     which
    became secondarily infected via some other, unknown, source.”
    Plaintiff eventually returned to work on 21 October 2011.
    On     15        February           2010,      Plaintiff           filed         a    workers’
    compensation claim.                Defendants denied the claim on 22 March
    2010.     On 15 February 2010, Plaintiff submitted a request to the
    -6-
    North Carolina Industrial Commission that his claim be assigned
    for hearing.
    On 14 March 2012, Plaintiff’s case was heard                      by Deputy
    Commissioner Robert J. Harris.               On 7 January 2013, the deputy
    commissioner      issued      an   Opinion    and    Award,     concluding      that
    Plaintiff had sustained a compensable injury to his lower back
    as   a   result   of    the    work-related        injury.      Based   on   these
    conclusions,      the   deputy       commissioner      issued     an    award     to
    Plaintiff that included (1) temporary total disability benefits
    for the period from 12 December 2009 through 4 February 2010;
    and (2) the requirement that Defendants pay                    for all medical
    treatment   he    had   received      from    11    December    2009    through   4
    February 2010.
    Defendants appealed the decision to the Full Commission,
    which heard the appeal on 12 June 2013.                On 16 August 2013, the
    Commission issued its Opinion and Award, with one commissioner
    dissenting,    affirming       the   deputy    commissioner’s      decision      and
    concluding, in pertinent part, as follows:
    1.   Based upon the preponderance of the
    evidence from the entire record, plaintiff
    has shown that he sustained a compensable
    injury to his low back by specific traumatic
    incident on 11 December 2009.
    2.   Based upon the preponderance of the
    evidence from the entire record, plaintiff
    -7-
    has shown that his continuing low back
    condition    after    11    December    2009,
    specifically the inflammatory process that
    required his December 2009 hospitalization
    and the ongoing treatment thereafter, was
    the result of a substantial aggravation of a
    pre-existing condition and/or was a direct
    and natural consequence of the 11 December
    2009 injury and was itself thus compensable.
    (Citations omitted.)    Defendants filed a timely notice of appeal
    to this Court.
    Analysis
    Defendants argue that the Commission erred in concluding
    that Plaintiff’s back condition was causally related to his 11
    December 2009 injury.   We disagree.
    Under the Workers’ Compensation Act, the claimant bears the
    burden of showing that the injury “arose out of and in the
    course of his employment.”    Lewis v. W.B. Lea Tobacco Co., 
    260 N.C. 410
    , 412, 
    132 S.E.2d 877
    , 879 (1963) (emphasis omitted).
    To be compensable an injury must spring from
    the employment or have its origin therein.
    An injury arises out of the employment when
    it is a natural and probable consequence or
    incident of the employment and a natural
    result of one of its risks, so that there is
    some causal relation between the injury and
    the performance of some service of the
    employment.

    Our review of an Opinion and Award by the Commission is
    “limited to consideration of whether competent evidence supports
    the    Commission's          findings       of    fact   and       whether    the        findings
    support the Commission's conclusions of law.”                                Richardson v.
    Maxim Healthcare/Allegis Grp., 
    362 N.C. 657
    , 660, 
    669 S.E.2d 582
    ,     584    (2008).            The    Commission’s         findings       of    fact      are
    conclusive on appeal if supported by competent evidence even if
    there is evidence to support contrary findings.                           Avery v. Phelps
    Chevrolet, 
    176 N.C. App. 347
    , 353, 
    626 S.E.2d 690
    , 694 (2006).
    On appeal, this Court will not “weigh the evidence and decide
    the issue on the basis of its weight.                         The court’s duty goes no
    further       than     to    determine         whether       the   record     contains       any
    evidence tending to support the finding.”                              Smith v. Champion
    Int’l,    134    N.C.       App.     180,      182,    
    517 S.E.2d 164
    ,       166    (1999)
    (citation and quotation marks omitted).
    When the Commission relies on expert medical testimony to
    make its findings, the expert’s testimony “must be such as to
    take    the     case      out   of       the     realm   of    conjecture          and    remote
    possibility”         in     order    to    constitute        competent       evidence       of   a
    causal relationship between the work-related incident and the
    injury.        Rogers v. Lowe’s Home Improvement, 
    169 N.C. App. 759
    ,
    -9-
    765, 
    612 S.E.2d 143
    , 147 (2005) (citation and quotation marks
    omitted).
    In the present case, among the findings of fact made by the
    Commission were the following:
    5.   Plaintiff had not had any significant
    low back problems at any time before 11
    December 2009. As of the occurrence of the
    incident in this claim, plaintiff was not
    having any physical problems, other than
    some residual impairment relating to an old
    work-related right ankle injury.   Plaintiff
    was physically active outside of work and
    worked out regularly.
    . . . .
    36. As Dr. Link wrote in a letter dated 20
    January 2010, “(Plaintiff) is a patient whom
    we are seeing in our office for epidural and
    left    paraspinous    muscle   inflammation,
    presumed to be an infectious process.    This
    developed    following   an   injury,   which
    occurred at work, and I feel is a direct
    result of his work-related injury.”    At his
    deposition, Dr. Link confirmed that he felt
    “fairly certain” of his opinion as stated in
    the letter.
    37. Regarding Dr. Dalton-Bethea’s conclusion
    that the infection pre-dated the dolly-
    lifting incident and that the incident
    merely brought the infection to light — that
    essentially plaintiff had a minor back
    strain and an infection simultaneously and
    that one had nothing at all to do with the
    other, or that plaintiff did not even suffer
    a minor back strain and just happened to
    first notice acute pain from an infection as
    he was lifting the dolly — Dr. Link felt
    that such a scenario was possible. Dr. Link
    -10-
    agreed that it was more likely than not that
    the infection did pre-date the incident,
    although he characterized the question of
    when   exactly   the   infection  began   as
    “unanswerable.”
    38. When asked in his deposition whether
    the dolly-lifting incident had a causal
    relationship to the condition for which
    plaintiff was hospitalized, Dr. Link stated
    that there were two possible scenarios —
    that the incident caused bruising, which
    pre-disposed plaintiff to the development of
    the infection; or that the infection was
    already in plaintiff’s system, which made
    his low back area vulnerable to an injury
    and a specific infection, and the incident
    “triggered” plaintiff’s condition.    As Dr.
    Link further testified, he could not “say
    with certainty either way” which scenario
    actually occurred.     The Full Commission
    finds that the occurrence of either scenario
    would be compensable, with the first being
    an infection that was a direct and natural
    result of a physical injury, and the second
    being a substantial aggravation of a pre-
    existing condition.
    . . . .
    41. As Dr. Derian testified, plaintiff’s
    findings    were    most     consistent     with
    underlying facet joint degeneration at L4-5
    and       L5-S1,        with       degenerative
    spondylolisthesis,    with     a   work-related
    injury on 11 December 2009, likely resulting
    in inflammation in that area, which became
    secondarily    infected    via    some    other,
    unknown, source.      As Dr. Derian further
    noted, there may have been gout involvement
    as well, as plaintiff had gout, which can
    degenerate a joint and thus make it more
    vulnerable   to   injury   and/or    create   an
    environment where infection can occur.
    -11-
    . . . .
    43. As Dr. Derian testified, the dolly-
    lifting    incident    was   a    symptomatic
    aggravation and/or activation of plaintiff’s
    underlying    gout-based   arthritis,    with
    subsequent severe inflammation, with or
    without    infection.       This    condition
    necessitated a very complex sequence of
    medical interventions that were required and
    that    induced   gradual   improvement    in
    plaintiff’s condition.
    44. The Full Commission accords more weight
    to the causation testimony of Drs. Link and
    Derian than to that of Drs. Priest and
    Dalton-Bethea.      Dr. Link was plaintiff’s
    treating physician throughout the entire
    episode,      beginning      early     in    his
    hospitalization.      Dr. Derian’s specialty is
    the lumbar spine, and his testimony about
    the   complex     process   that    occurred  in
    plaintiff’s low back in this matter was
    thoughtful, cogent and convincing.           Dr.
    Priest    did     not    become    involved   in
    plaintiff’s     treatment    until    after  his
    hospitalization.       Dr. Dalton-Bethea is a
    pain management specialist, while Drs. Link
    and Derian bring specialties to bear that
    are more directly applicable to the facts of
    this claim.
    . . . .
    46. Plaintiff’s medical treatment for his
    low   back   condition   at   Forsyth    Medical
    Center,    his   hospitalization,     and    his
    treatment and diagnostic testing and imaging
    with   and/or   at   the   direction    of   Dr.
    Galbreath and the physicians with Infectious
    Disease Specialists, through 4 February
    2010, was all reasonably required to effect
    -12-
    a cure, provide relief and/or lessen            the
    period of plaintiff’s disability.
    Based     on   these   factual     findings,   the   Commission   made
    conclusions of law stating, in pertinent part, as follows:
    2. Based upon the preponderance of the
    evidence from the entire record, plaintiff
    has shown that his continuing low back
    condition    after   11    December    2009,
    specifically the inflammatory process that
    required his December 2009 hospitalization
    and the ongoing treatment thereafter, was
    the result of a substantial aggravation of a
    pre-existing condition and/or was a direct
    and natural consequence of the 11 December
    2009 injury and was itself thus compensable.
    . . .
    3.   Plaintiff has the burden of showing he
    is unable to earn the same wages he earned
    before the injury, either in the same
    employment or in other employment. . . .
    Plaintiff can meet this burden in one of
    four ways: (1) the production of medical
    evidence that he is physically or mentally,
    as a consequence of the injury, incapable of
    any   employment;   (2)  the  production   of
    evidence that he is capable of some work,
    but that he has, after a reasonable effort,
    been unsuccessful in obtaining employment;
    (3) the production of evidence that he is
    capable of some work but that it would be
    futile to seek other employment because of
    preexisting     conditions,    i.e.,     age,
    inexperience, lack of education; or (4) the
    production of evidence that he has obtained
    other employment at a wage less than that
    earned prior to the injury. Russell v. Lowes
    Product Distrib., 
    108 N.C. App. 762
    , 
    425 S.E.2d 454
    (1993).
    -13-
    4.   Plaintiff has met his burden of proving
    disability under prong (1) of Russell by
    demonstrating that he was entirely unable to
    work from    12   December 2009 through 4
    February 2010.     He is thus entitled to
    receive     temporary     total   disability
    compensation for said period. N.C. Gen.
    Stat. §§ 97-2(9) and 97-29; Russell v. Lowes
    Product Distrib., 
    108 N.C. App. 762
    , 
    425 S.E.2d 454
    (1993).
    Defendants     challenge      the       Commission’s      determination        that
    Plaintiff’s    workplace         injury       caused    or    exacerbated      his   back
    condition, arguing that the medical testimony in this case was
    insufficient to establish causation to the degree required under
    the Workers’ Compensation Act.                 Defendants state in their brief
    that they are challenging findings of fact 5, 36-38, 41, 43-44,
    and 46 and conclusions of law 2-3.                     In essence, however, their
    entire   argument     on    appeal       is    that     the   Commission       erred    in
    relying on the opinions of Drs. Link and Derian because the
    opinions    expressed       by    these       two   doctors     were      impermissibly
    speculative.        Therefore, Defendants argue, Plaintiff failed to
    establish     the     causal      connection           necessary     to       support    a
    conclusion that Plaintiff suffered a compensable injury under
    the Workers’ Compensation Act.                We disagree.
    Our   Supreme       Court    has    made      clear     that     “(1)    the   Full
    Commission is the sole judge of the weight and credibility of
    the   evidence,     and    (2)    appellate         courts    reviewing       Commission
    -14-
    decisions     are      limited    to    reviewing       whether       any     competent
    evidence supports the Commission's findings of fact and whether
    the findings of fact support the Commission's conclusions of
    law.”     Deese v. Champion Int'l Corp., 
    352 N.C. 109
    , 116, 
    530 S.E.2d 549
    , 553 (2000).
    Here,      the   Commission      made   it     clear    that    it    deemed   Dr.
    Derian’s and Dr. Link’s testimony to be credible.                      In conclusion
    of law 2, the Commission determined that Plaintiff’s lower back
    inflammation that resulted in his hospitalization and continued
    treatment following discharge “was the result of a substantial
    aggravation of a pre-existing condition and/or was a direct and
    natural    consequence      of    the   11    December       2009    injury    and   was
    itself    thus    compensable.”         In    reaching       this    conclusion,     the
    Commission       elected   to    give    greater      weight    to    the     causation
    testimony of Drs. Link and Derian than to that of Drs. Priest
    and   Dalton-Bethea.         In     finding     of    fact    44,    the    Commission
    stated:
    Dr. Link was plaintiff’s treating physician
    throughout the entire episode, beginning
    early in his hospitalization.  Dr. Derian’s
    specialty is the lumbar spine, and his
    testimony about the complex process that
    occurred in plaintiff’s low back in this
    matter    was   thoughtful,   cogent    and
    convincing.   Dr. Priest did not become
    involved in plaintiff's treatment until
    after his hospitalization.     Dr. Dalton-
    -15-
    Bethea is a pain management specialist,
    while Drs. Link and Derian bring specialties
    to bear that are more directly applicable to
    the facts of this claim.
    Competent evidence supports this finding.                    When asked if he
    had an opinion about whether there was a relationship between
    Plaintiff’s     injury    and    his   lower       back   condition,   Dr.   Derian
    testified as follows:
    My   opinion   is   that   I   believe  that
    [Plaintiff] had underlying degeneration of
    facets and the disk areas at L4-5, and L5-
    S1, the lower two areas of the low back;
    that his lifting injury resulted in . . . an
    environment that then subsequently resulted
    in an infection. I think it is likely that
    he got a hematoma, or that he tremendously
    inflamed an area . . . where gout was
    involved with his spine. Both infection and
    gout are unproven in this case; neither one
    of those has been proven, because we don’t
    know that that is how it happened, despite
    all the treatment . . . like I described
    earlier. And that in the absence of injury,
    he may have never had these symptoms.
    Defendants         argue   that    Dr.    Derian’s     testimony   amounts     to
    mere speculation concerning the cause of Plaintiff’s condition
    and, for this reason, is insufficient to establish causation.
    However, in order for expert medical testimony to constitute
    competent evidence on which the Commission may rely, “testimony
    attesting   to    medical      certainty      is    not   required.”      Adams    v.
    Metals   USA,    168    N.C.    App.   469,    482-83,     
    608 S.E.2d 357
    ,    365
    -16-
    (explaining that “[t]he fact that the treating physician in this
    case    could   not    state    with   reasonable     medical   certainty      that
    plaintiff's accident caused his disability, is not dispositive —
    the degree of the doctor's certainty goes to the weight of his
    testimony” (citation omitted)), aff’d per curiam, 
    360 N.C. 54
    ,
    
    619 S.E.2d 495
    (2005).          Rather, as we have stated,
    our Supreme Court has created a spectrum by
    which to determine whether expert testimony
    is sufficient to establish causation in
    worker’s    compensation   cases.      Expert
    testimony that a work-related injury “could”
    or “might” have caused further injury is
    insufficient to prove causation when other
    evidence shows the testimony to be “a guess
    or mere speculation.”    However, when expert
    testimony establishes that a work-related
    injury   “likely”   caused   further  injury,
    competent evidence exists to support a
    finding of causation.

    , 446-47 (citation omitted), disc. review denied,
    
    360 N.C. 61
    , 
    621 S.E.2d 177
    (2005).
    Although Plaintiff had a negative aspirate for infection in
    his    spine,   this   did     not   prevent    Dr.   Derian,   a    lumbar    spine
    specialist,     from    determining      that    Plaintiff’s        injury    likely
    caused his lower back condition.                 Dr. Derian testified that
    while
    [Plaintiff] is not documented as having an
    infection or gout, . . . he had findings
    -17-
    consistent with either gout or infection
    superimposed on degeneration problems of
    spondylolisthesis   at   L4-5,    structurally
    severe facet joint degeneration at L4-5,
    disk degeneration, and spinal stenosis at
    L4-5, L5-S1, with a disk rupture.
    When    asked     if    he    had     an    opinion      concerning        whether
    Plaintiff’s       injury     resulted       in    his     ensuing        symptoms    and
    treatment, Dr. Derian answered affirmatively and testified as
    follows:
    I think that his injury resulted in either
    primary inflammation, hematoma, infection,
    activation of disk degeneration, infection,
    and/or gout, and that this resulted in a
    very    complex    sequence     of    medical
    interventions that were required, including
    initial treatment and then the intermediate
    recovery period,    where inflammation was
    diminishing, as documented by MRI scans
    twice in 2010, and then the recovery . . . .
    “The    decision       concerning       what      weight     to     give   expert
    evidence     is   a   duty   for    the    Commission     and      not   this    Court.”
    
    Adams, 168 N.C. App. at 483
    , 608 S.E.2d at 365.                          As long as a
    qualified expert “bases his or her opinions on evidence properly
    contained in the record, the Commission is entitled to rely on
    that testimony in making its decision.”                   Huffman v. Moore Cty.,
    208   N.C.   App.     471,   490,    
    704 S.E.2d 17
    ,   30   (2010)    (citation
    omitted),     disc. review denied, 
    365 N.C. 328
    , 
    717 S.E.2d 397
    (2011).      Dr. Derian’s testimony was based on his evaluation of
    -18-
    Plaintiff as well as his review of Plaintiff’s medical records
    and   constituted          more    than      mere    speculation.          Thus,    the
    Commission was permitted to rely on Dr. Derian’s testimony as to
    causation.
    We likewise reject Defendants’ similar argument regarding
    the   Commission’s         reliance     on    Dr.    Link’s     testimony.     In   his
    deposition, when asked whether there was a relationship between
    Plaintiff’s injury and his subsequent lower back condition, Dr.
    Link testified:
    Well, I think it’s an unanswerable question.
    You know, I think it’s a possibility that
    when he did the lifting he caused some
    bruising,   and  that   predisposed  him  to
    getting an infection in that area. I think
    it’s also possible that it could have been a
    preexisting infection, and when he did the
    lifting, it triggered pain because the area
    was vulnerable to the infection.
    Defendants argue that Dr. Link’s testimony was speculative
    because he could not testify to a reasonable degree of medical
    certainty      which       of     the   two     scenarios       actually     occurred.
    However, in finding of fact 38 the Commission recognized that
    “the occurrence of either scenario would be compensable, with
    the   first    being       an   infection     that    was   a   direct   and   natural
    result of a physical injury, and the second being a substantial
    aggravation     of     a    pre-existing       condition.”        (Emphasis    added.)

    See 
    Smith, 134 N.C. App. at 182
    , 517 S.E.2d at 166 (holding
    work-related injury that               aggravated preexisting condition was
    compensable under Workers’ Compensation Act).
    While    there     may    have    been      conflicting     medical         testimony
    about    the    causal     relationship          between      Plaintiff’s          low    back
    condition and his work-related injury, it was for the Commission
    to weigh the credibility of the witnesses and render a decision.
    The    testimony     of   Drs.        Derian    and   Link      served   as    sufficient
    evidence      to   support      the     Commission’s         findings     of       fact    and
    conclusions of law challenged by Defendants.                             The Commission
    chose to give more weight to the testimony of Drs. Derian and
    Link than to the testimony of Drs. Dalton-Bethea and Priest.                                We
    lack the authority to second-guess its determination as to the
    proper weight to be accorded the medical testimony.                            See Chavis
    v. TLC Home Health Care, 
    172 N.C. App. 366

    ,

    fact    are    conclusive       on     appeal      when    supported      by       competent
    evidence      even   if    there       is   evidence       to    support       a    contrary
    finding”       (citation        and     quotation      marks       omitted)),            appeal
