    OPINION
    ¶1    The claimant, Steven Dunteman, filed an application for adjustment of claim
    pursuant to the Workers' Compensation Act (Act) (820 ILCS 305/1 et seq. (West 2010)),
    seeking benefits for injuries he allegedly sustained on June 21, 2011, while working for
    the employer, Caterpillar, Inc. The parties stipulated that on June 21, 2011, the claimant
    sustained an accidental injury arising out of and in the course of his employment. After a
    1
    hearing, an arbitrator found that the claimant's current condition of ill-being was causally
    related to the accident and awarded him reasonable and necessary medical expenses,
    temporary total disability (TTD) benefits, and permanent partial disability (PPD) benefits.
    ¶2     A majority of the Illinois Workers' Compensation Commission (Commission)
    reversed the arbitrator's decision and vacated the awards of compensation, finding that
    the claimant suffered a work-related injury on July 21, 2011, but that his self-treatment of
    the work-related injury constituted an intervening accident that broke the chain of
    causation between his work-related blister and subsequent infection. The dissenting
    Commissioner believed the claimant's infection was a foreseeable and natural
    consequence of the work-related blister and that his self-treatment was not an intervening
    accident that broke the chain of causation.
    ¶3     On judicial review, the circuit court of Macon County confirmed the
    Commission's decision. The claimant filed a timely appeal. For the reasons that follow,
    we reverse and remand for further proceedings.
    ¶4                                   BACKGROUND
    ¶5     On October 19, 2011, the claimant filed an application for adjustment of claim
    pursuant to the Act, seeking benefits for injuries he allegedly sustained on June 21, 2011,
    while working for the employer. The following factual recitation is taken from the
    evidence presented at the June 13, 2013, arbitration hearing.
    ¶6     During a 1999 Department of Transportation (DOT) physical examination, the
    claimant was found to have above normal blood sugar levels.              The DOT doctor
    encouraged him to improve his dietary habits but did not recommend any other treatment
    2
    or modifications.    The claimant testified that he followed the doctor's advice and
    improved his eating habits.     He stated that, between 1999 and 2008, he felt good,
    continued monitoring his diet, and had no issue with his blood sugar levels.
    ¶7     The claimant testified that he was first diagnosed with type II diabetes in October
    2009 when he sought treatment for an unrelated work accident. When he saw his primary
    care doctor, Dr. Daniel Smith, on November 9, 2009, Dr. Smith noted that his blood
    sugar levels were elevated, that he was "trying to work on his diet," and that he continued
    "to be under a lot of stress." He began taking Metformin to reduce his blood sugar levels.
    ¶8     When the claimant saw Dr. Smith again on January 26, 2010, he had fluctuating
    blood sugar levels. Dr. Smith noted that the claimant continued monitoring his diet and
    that his diabetes was "under fair control."
    ¶9     The claimant testified that he continued taking Metformin and that he also began
    testing his blood sugar levels at home twice a day. He stated that he continued following-
    up with Dr. Smith and noticed that his blood sugar levels were dropping below normal.
    He testified that, after consulting with Dr. Smith, he stopped taking Metformin and
    regulated his blood sugar levels with a controlled diet between July 2010 and June 2011.
    ¶ 10   The parties stipulated that on June 21, 2011, the claimant sustained an accidental
    injury arising out of and in the course of his employment. At that time, he was working
    for the employer as an "outside driver." The automatic truck he usually drove was being
    repaired and in May 2011 was replaced with an older 10-speed truck, which required him
    to strike a manual clutch with his left foot about 200 times per shift. He struck the clutch
    forcefully with the bottom of his left foot because the clutch did not engage properly. He
    3
    wore steel-toed boots, but the bottom was rubber with no additional protection. He spent
    approximately 70% of the workday driving the truck and 30% of the day exiting the truck
    to perform tasks outside the truck. When exiting the truck, which he did about 30 times
    per day, he stepped onto a steel, ridged corrugated step and spun on the left upper portion
    of his foot, in the same area where his foot struck the clutch. On or about June 21, 2011,
    he noticed that the bottom pad of his left foot was sore. He continued performing his
    normal work duties, working 12-hour shifts for the next 9 or 10 days. He wore cotton
    socks with his work boots but continued having pain and problems with his left foot.
    Striking the clutch worsened the pain, and he began walking with a limp.
    ¶ 11   The claimant testified that on or about June 25, 2011, while bathing, he noticed a
    water blister under the callus on the bottom of his left foot between his third and fourth
    toes. He went to the kitchen, sterilized a needle by boiling it in hot water on the stove,
    propped up his foot, and inserted the needle to relieve the pressure of the water blister.
    He testified that pure "water" drained from the blister. He then used peroxide on a cotton
    swab to wipe the area. He indicated that he had performed this procedure, which his
    mother had taught him at a young age, many times in the past without complications. He
    stated that no physician had ever told him not to pop blisters on his foot in this manner.
    ¶ 12   On Dr. Smith's recommendation, the claimant resumed taking Metformin on June
    28, 2011, to regulate his elevated blood sugar levels. According to the claimant, this was
    the first time he had been on medication in about one year because he had been able to
    regulate his diabetes with a controlled diet.
    4
    ¶ 13   On July 1, 2011, the claimant called Dr. Smith to schedule an appointment. Dr.
    Smith's records indicate that the claimant had a sore on his foot, which he was worried
    about getting infected, and that his foot was bruised under his callus.
    ¶ 14   The claimant testified that on July 4, 2011, his left foot was red and swollen
    around the blister. Because he could not immediately get in to see Dr. Smith, he went to
    St. Mary's Hospital, where he saw Dr. Brooke Ballard. He reported a 2-day history of
    fever with chills and a 4-day history of increasing left foot pain with swelling and
    redness. He noted that 7 to 10 days earlier, he had driven a clutch transmission semi-
    truck at work and developed a callus on the bottom of his left foot over the fourth
    metatarsal region. He found a blister and opened it himself. Several days later, the top of
    his foot was turning red, with swelling and warmth. He had been unable to work that day
    because of increased pain. Dr. Ballard noted a past medical history of type II diabetes
    and a November 2009 hospitalization for cellulitis of his right lower extremity. On
    examination, she found that he was swollen just below his left knee down to his toes. He
    had a callus on the bottom of his left foot, redness and warmth on the top of his left foot
    affecting the second and third toes, and tenderness to palpation throughout.
    ¶ 15   That same day, the claimant saw Dr. Jason Anderson, a podiatrist at St. Mary's
    Hospital. He reported that about a week and a half prior, he had noticed a blister on the
    bottom of his foot and had used a sterilized needle to drain the blister. He indicated that
    he had not had a left leg infection like this in the past but that he did have a prior history
    of infection to his right leg after a blow to the leg by a large metal object. His blood
    sugar level was 361, which indicated uncontrolled diabetes.           On examination, Dr.
    5
    Anderson found significant deep redness on the top of his left foot with lymphangitis and
    lymphadenopathy in both the inguinal and popliteal glands. There was a thick callus sub
    third metatarsal head extending distal lateral to the fourth digit on the bottom of his left
    foot. Dr. Anderson debrided in the area of the third metatarsal head and found a full
    thickness ulceration that was malodorous and measured two centimeters in diameter with
    a necrotic fibrotic base. The claimant was diagnosed with severe cellulitis left extremity
    with low grade temperature, lymphadenopathy, and diabetes with loss of protective
    sensation. He was admitted to the hospital and put on broad spectrum antibiotics.
    ¶ 16   On July 5, 2011, the claimant underwent his first surgery performed by Dr.
    Anderson, an incision and drainage of the deep abscess of his left foot third interspace
    with debridement of the tendon and fascia and delayed closure.              According to the
    operative report, attention was focused on the bottom of his foot where the ulceration was
    noted. Dr. Anderson performed incisions "encompassing" the ulceration, which was
    directly beneath the third metatarsal head.
    ¶ 17   On July 6, 2011, the claimant underwent a second surgery performed by Dr.
    Anderson, a secondary irrigation and debridement with delayed closure. His diagnosis
    was "deep abscess left foot," and his third toe had venous congestion. His cellulitis
    improved, and he was discharged from the hospital on July 8, 2011, with instructions to
    take oral antibiotics, follow a diabetic diet, and regularly test his blood sugar levels.
    ¶ 18   The claimant saw Dr. Anderson again on August 2, 2011. The doctor noted that
    the distal aspect of his third toe was completely "gangrenous" and "necrotic." On August
    5, 2011, the claimant underwent a third surgery performed by Dr. Anderson, a left third
    6
    toe amputation with medial based toe flap closure and deep interspace debridement in the
    left third interspace. His diagnoses were left third toe necrosis and cellulitis.
    ¶ 19   Dr. Anderson took the claimant off work on July 4, 2011, and released him to
    return to work effective September 5, 2011. At that time, he returned to full duty work
    with no restrictions.
    ¶ 20   When the claimant saw Dr. Anderson again on September 20, 2011, the redness
    and swelling had resolved, and no new lesions or open ulcerations were present. Dr.
    Anderson noted that the claimant's job put him at risk for these ulcerations because he
    had to use his left foot not only to clutch but also to get in and out of the truck. The
    doctor opined that "[t]his is most likely the cause of his original ulceration" and that
    "there would have been no reason for him to suffer a large callus without the direct
    mechanism and repetitive mechanism."
    ¶ 21   On February 7, 2012, at his attorney's request, the claimant underwent an
    independent medical examination by Dr. Jeffrey Coe, a board certified occupational
    medicine specialist. Dr. Coe testified by evidence deposition that he considered the
    history the claimant gave him, the treatment records from St. Mary's Hospital and Dr.
    Anderson, and his own clinical examination of the claimant. Dr. Coe testified, to a
    reasonable degree of medical certainty, that there was a causal relationship between the
    nature of the claimant's work with the employer involving the repetitive clutch depression
    and exiting of the truck and his current condition of ill-being of his left foot. Dr. Coe
    described the claimant's diabetes as mild because he was not insulin-dependent,
    controlled his blood sugar levels with diet only, and had no known complications
    7
    associated with diabetes. Dr. Coe testified that the claimant had a higher risk of infection
    as a result of his diabetes but opined that he would not have developed the infection if he
    had not developed a blister from his work activities. Dr. Coe opined that "the infection
    arose from the penetration of the blister in his left foot with a needle."
    ¶ 22   Dr. Coe stated that the claimant's prognosis was excellent. The wound was healed,
    and he had returned to full activities, but he did have changes in sensation and balance as
    well as a flexion contracture, or hammer toe deformity, in his left second toe.
    ¶ 23   On May 25, 2012, at the employer's request, the claimant underwent an
    independent medical examination by Dr. Ernest Chiodo, who is board certified in internal
    medicine, occupational and environmental medicine, and public health and epidemiologic
    medicine. Dr. Chiodo, who testified by evidence deposition, found no causal relationship
    between the surgeries and the claimant's work duties and asserted that the claimant's
    infection "happened on the top of his foot, not on the bottom." Although Dr. Chiodo
    acknowledged that the claimant's repetitive use of the clutch caused the blister and that
    once a blister has formed, complications can arise from it, he believed that neither the
    blister nor the lancing of the blister contributed to the claimant's foot infection.
    ¶ 24   Dr. Chiodo testified that the claimant had uncontrolled diabetes and was not
    exercising diabetic foot care. He testified that the claimant had roughened and chapped
    feet with slight cracking of the top of his left foot. On examination, Dr. Chiodo found
    brownish discoloration consistent with atrophic changes involving the left foot consistent
    with poor blood supply in addition to the lack of any diabetic foot care. Based on the
    medical records and history of poor foot care, Dr. Chiodo opined that the infection
    8
    occurred on the top of the foot originally due to uncontrolled diabetes and lack of proper
    diabetic foot care and that there was no causal connection between the infection and the
    blister on the bottom of his foot. Dr. Chiodo stated that "there is the very plausible
    alternative explanation of bacterial intrusion through cracked, roughened skin in an area
    on the top of his foot remote from the blister." Although Dr. Chiodo believed the
    cellulitis was causally connected with the amputation of the toe, he did not believe the
    cellulitis was work related.
    ¶ 25   The claimant testified that he listened to and followed Dr. Smith's orders when it
    came to the treatment of his diabetes. He stated that he had not taken Metformin since
    September 2012 because he had lost weight and was able to control his diet. He testified
    that he would resume taking Metformin if Dr. Smith recommended it but that no doctor
    had recommended that he resume taking medication to control his blood sugar.
    ¶ 26   The claimant returned to work with the employer on September 5, 2011, keeping
    the same job title. He testified that he was currently working a 40-hour work week, with
    no restrictions or assistance. His current job duties were similar to his duties before the
    work accident, but he was now driving an automatic "jockey truck." He was in a
    different department, which required transporting frames, which was lighter duty work
    than his prior position. He did not have to move as much in his current position.
    ¶ 27   The claimant testified that, after his foot surgeries, it was harder to get up after
    being on his knees because he could not put as much pressure on the amputation site due
    to the immense pain it caused. He had to adjust the manner in which he got up from this
    position. He testified regarding issues concerning his balance, in that he wobbled if he
    9
    did not put pressure on his left foot, but the pressure caused pain. He stated that cold
    temperatures caused discomfort in his foot and that the scarred area became numb.
    ¶ 28   The claimant offered into evidence invoices for medical expenses he had incurred
    as a result of the foot treatment, noting an outstanding balance of $2,117.13.           The
    remaining medical bills had been paid through the employer's group insurance carrier.
    ¶ 29   On August 8, 2013, the arbitrator filed a decision, finding that on June 21, 2011,
    the claimant sustained an accidental injury arising out of and in the course of his
    employment and that his current condition of ill-being was causally related to the
    accident. More specifically, the arbitrator found that the claimant suffered from a work-
    related blister, which he self-treated in a sterile manner, and subsequently developed an
    infection resulting in multiple surgeries and the amputation of his third, middle toe.
    ¶ 30   The arbitrator found that the claimant did not commit an injurious practice under
    section 19(d) of the Act (820 ILCS 305/19(d) (West 2010)). The arbitrator noted that the
    claimant was informed of an elevated blood sugar level in 1999 and took reasonable
    measures to treat the condition, which included dietary changes, lifestyle modifications,
    and a reduction of his daily stresses. In 2009, he was diagnosed with type II diabetes; it
    was recommended that he begin treatment for that condition; and he immediately did so
    with Dr. Smith. The arbitrator found that there was nothing in Dr. Smith's medical
    records to indicate a failure to comply, treat, or otherwise follow the appropriate protocol.
    To the contrary, the claimant began taking medication, had regular follow-up visits,
    monitored his blood sugar levels daily, and continued monitoring his diet. It was only
    after his blood sugar levels dropped that he stopped taking the medication. His blood
    10
    sugar levels spiked again after the left foot injury, and he again followed-up with Dr.
    Smith. The arbitrator found that, contrary to Dr. Chiodo's opinion, the record shows that
    the claimant followed-up with medical supervision and medications and monitored his
    diet, weight, and blood sugar levels once he was diagnosed with diabetes. The arbitrator
    found that there was no indication of non-compliance or any failure to appropriately treat
    his diabetes. The arbitrator, thus, found that the claimant's conduct in this regard did not
    rise to the level of an injurious practice under section 19(d).
    ¶ 31   The arbitrator also found that the claimant's lancing of his blister did not rise to the
    level of an injurious practice. The arbitrator noted that the un-rebutted testimony shows
    that the claimant popped his blister using a home remedy technique in a sanitary fashion.
    The arbitrator found that it was not unreasonable for a person to "pop" what appears to be
    a "water blister" with a sanitary needle. The arbitrator noted that, although the claimant
    did suffer from diabetes, the un-rebutted testimony shows that neither his treating
    physician, nor any other doctor, ever told him not to "pop" his blisters in this way.
    ¶ 32   The arbitrator awarded the claimant TTD benefits of $475.87 per week for 9
    weeks from July 4 through September 4, 2011; PPD benefits of $428.29 per week for
    46.4 weeks because the injuries sustained caused the 100% loss of use of the third toe and
    the 20% loss of use of the left foot; and $2,117.13 in medical expenses.
    ¶ 33   The employer sought review of the arbitrator's decision before the Commission.
    On December 10, 2014, a majority of the Commission reversed the arbitrator's decision
    and vacated the awards of compensation, reasoning as follows:
    11
    "[T]he parties stipulated that [the claimant's] work activities caused the
    development of the blister. However, *** the infection did not come from the
    existence of the blister, but from [the claimant's] lancing of the blister, which
    constitutes an intervening accident that breaks the causal chain between the
    development of the blister and [his] current condition of ill-being. The blister, in
    and of itself, did not lead to the infection. [The claimant's] actions lead [sic] to the
    infection, and the infection is what led to the amputation of [his] left third toe.
    There is nothing in the record to indicate that the infection was a result of
    [the claimant's] work with [the employer]. Instead, as explained above, the record
    points to [the claimant's] lancing of the blister, and not the blister itself, as the
    cause of [his] left foot infection. Therefore, *** the Commission finds that the
    infection, and not the blister, caused [his] left foot condition and, ultimately, the
    amputation of [his] left third toe.      As a result, [he] failed to prove that the
    development of the blister at work is causally related to [his] need for treatment of
    an infection, the amputation of his toe, and his current condition of ill-being.
    Therefore, the Commission reverses the Arbitrator's finding regarding causal
    connection and finds that [the claimant's] current condition of ill-being is not
    causally related to the June 21, 2011 accident."
    ¶ 34   In response to the employer's argument that the claimant engaged in injurious
    practices under section 19(d) of the Act by lancing the blister, the Commission stated:
    "[Section 19(d)] deals with a claimant negatively affecting his/her recovery.
    It does not deal with a claimant's actions as the cause of his/her injuries or a
    12
    claimant's behavior severing the causal connection between a work accident and
    the claimant's condition of ill-being. Therefore, Section 19(d) *** does not apply
    to the case at bar."
    ¶ 35   The dissenting Commissioner would have upheld the arbitrator's decision. In his
    view, the claimant's "lancing the blister in a sterile manner does not constitute an
    intervening accident" but was, instead, "a natural consequence of the work-related
    injury." According to the dissent, if the claimant had not incurred the work-related
    blister, his foot would not have become infected, and no amputation would have been
    required. The dissent noted that applicable case authority requires that the intervening
    accident must completely break the causal chain between the injury and ensuing
    condition and that the accidental injury need only be a causative factor in the resulting
    condition of ill-being. The dissent concluded that the stipulated work-related accident led
    to a blister, which was a causative factor in the claimant's resulting infection, and that it is
    foreseeable that a blister will become infected.
    ¶ 36   The claimant filed a timely petition for judicial review in the circuit court, which
    confirmed the Commission's decision on June 15, 2015. This appeal followed.
    ¶ 37                                    ANALYSIS
    ¶ 38   Prior to reaching the merits of this appeal, we must first determine the appropriate
    standard of review. The employer argues that causation is a question of fact and that the
    appropriate standard of review is, therefore, whether the Commission's finding was
    against the manifest weight of the evidence. The claimant asserts, however, that he does
    not dispute any of the Commission's factual findings, including its finding that his
    13
    lancing of his work-related blister with a sterilized needle caused his infection. He
    argues that, because the facts determined and relied upon by the Commission are
    undisputed on appeal, the Commission's finding with regard to causation presents a
    question of law subject to de novo review. We agree with the employer.
    ¶ 39   Causation, including the existence of an independent intervening cause, is a
    question of fact for the Commission, and its finding in that regard will not be reversed on
    appeal unless it is against the manifest weight of the evidence. Global Products v.
    Workers' Compensation Comm'n, 
    392 Ill. App. 3d 408
    , 411, 
    911 N.E.2d 1042
    , 1046
    (2009).
    ¶ 40   To obtain compensation under the Act, a claimant must show, by a preponderance
    of the evidence, that he suffered a disabling injury that arose out of and in the course of
    his employment. Sisbro, Inc. v. Industrial Comm'n, 
    207 Ill. 2d 193
    , 203, 
    797 N.E.2d 665
    ,
    671 (2003).     The "in the course of" component refers to the time, place, and
    circumstances under which the injury occurred. 
    Id. The "arising
    out of" component
    addresses the causal connection between a work-related injury and the claimant's current
    condition of ill-being. 
    Id. at 203,
    797 N.E.2d at 672. An injury "arises out of" one's
    employment if it "had its origin in some risk connected with, or incidental to, the
    employment so as to create a causal connection between the employment and the
    accidental injury." 
    Id. ¶ 41
      Here, the parties stipulated that on June 21, 2011, the claimant sustained an
    accidental injury that arose out of and in the course of his employment. However, the
    employer argues that the work-related blister was not causally related to the subsequent
    14
    infection. The Commission agreed, finding that the claimant's lancing of the blister, and
    not the blister itself, caused his infection and that this was an independent intervening
    accident that broke the chain of causation between the blister and subsequent infection.
    ¶ 42   "Every natural consequence that flows from an injury that arose out of and in the
    course of one's employment is compensable under the Act absent the occurrence of an
    independent intervening accident that breaks the chain of causation between the work-
    related injury and an ensuing disability or injury." National Freight Industries v. Illinois
    Workers' Compensation Comm'n, 
    2013 IL App (5th) 120043WC
    , ¶ 26, 
    993 N.E.2d 473
    .
    "Under an independent intervening cause analysis, compensability for an ultimate injury
    or disability is based upon a finding that the employee's condition was caused by an event
    that would not have occurred 'but for' the original injury." 
    Id. ¶ 43
      "For an employer to be relieved of liability by virtue of an intervening cause, the
    intervening cause must completely break the causal chain between the original work-

    ¶ 45   A review of the record in this case demonstrates that there is clearly a "but-for"
    relationship between the claimant's work-related blister and subsequent infection. Quite
    simply, even if the claimant's lancing of the work-related blister with a sterilized needle
    was the immediate cause of his infection, as the Commission found, the infection would
    not have occurred "but for" the existence of the work-related blister. That is because "but
    for" the existence of the work-related blister, there would have been no blister to lance.
    His employment, therefore, remains a cause of his current condition of ill-being. The
    Commission's finding that the claimant's self-treatment was an independent intervening
    accident that broke the chain of causation between his work-related blister and
    subsequent infection was, therefore, against the manifest weight of the evidence.
