Evaluation and Management of Acute Foot Pain and Substance-Related Neuropathy

Clinical Evaluation of Eversion Pain

  • The American Academy of Family Physicians recommends palpatation of the peroneal tendons along the lateral aspect of the foot and ankle to identify localized tenderness that reproduces the pain experienced during activity 1
  • The American Academy of Family Physicians suggests examining for swelling, erythema, or asymmetry compared to the contralateral foot, which are common signs of tendinopathy 1
  • The American Academy of Family Physicians advises testing active and passive range of motion in eversion, which is typically limited on the symptomatic side 1
  • The American Academy of Family Physicians recommends performing tendon loading maneuvers by asking for eversion against resistance to reproduce the characteristic pain 1
  • The American College of Radiology suggests applying the Ottawa rules to determine if radiographs are necessary, with a sensitivity of 99% for ruling out a fracture 2
  • The American Diabetes Association recommends determining if the pain is distal, symmetrical, and worsens at night, which are typical characteristics of painful peripheral neuropathy 5
  • The American Diabetes Association advises looking for specific descriptors such as burning sensations, sharp pains, and paresthesias, which indicate small fiber involvement 5
  • The American Academy of Neurology suggests evaluating small fiber function with pinprick and temperature sensation tests on the toes and soles of the feet 6
  • The American Academy of Neurology recommends evaluating large fiber function with a 128 Hz tuning fork for vibration and testing ankle reflexes 6

Paraclinical Evaluation

  • The American Academy of Family Physicians recommends prioritizing laboratory tests such as hemoglobin A1c or fasting glucose to screen for diabetes, the most common cause of peripheral neuropathy 6
  • The American Academy of Family Physicians suggests testing vitamin B12 levels, as a deficiency can cause sensory neuropathy 6
  • The American Thyroid Association recommends evaluating thyroid function, as hypothyroidism can cause neuropathy 6
  • The American College of Radiology advises that radiographs of the foot are only necessary if the Ottawa rules are positive 2

Treatment Algorithm

  • The American Academy of Family Physicians recommends relative rest, oral nonsteroidal anti-inflammatory drugs (NSAIDs), and topical NSAIDs for the treatment of tendinopathy 1
  • The American Academy of Family Physicians suggests a PRICE protocol (protection, rest, ice, compression, elevation) for the treatment of tendinopathy 4
  • The American Academy of Neurology recommends immediate cessation of the triggering substance and topical treatments for the treatment of substance-related neuropathy 5
  • The Mayo Clinic Proceedings advises avoiding prolonged immersion in cold water or ice, as this can increase the risk of tissue damage, ulcers, and disability 7

Chronic Phase

  • The American Academy of Family Physicians recommends extracorporeal shock wave therapy as a safe, non-invasive, and effective option for chronic tendinopathy, although it can be costly 1
  • The American Academy of Family Physicians suggests surgery as an effective option for carefully selected patients who have failed 3-6 months of conservative therapy 1
  • The Mayo Clinic Proceedings recommends a multidisciplinary approach with referral to a pain rehabilitation center for severe, refractory, or disabling cases of neuropathy 7
