What Is Tarsal Tunnel Syndrome?

Tarsal tunnel syndrome is irritation to the posterior tibial nerve causing pain, numbness and tingling along the path of the nerve in the foot and leg.

Tarsal tunnel syndrome is compared to carpal tunnel syndrome occurring in the wrist.  Both are caused by compression of a nerve in a small confined space causing pain and discomfort.

Symptoms

  • Tingling, burning sensation (“electrical shock”)
  • Numbness
  • Shooting pain to the leg or toes
  • Swelling of the ankle with above symptoms
    If left untreated this condition can lead to permanent nerve damage of the nerve involved

Causes

  • Flat feet
  • Varicose veins
  • Ganglion cyst
  • Inflammation of a tendon
  • Bone spur
  • Trauma or injury (ie: Ankle Sprain)
  • Systemic diseases such as diabetes or arthritis can cause swelling, thus compressing the nerve

Diagnosis

  • MRI – If a mass is suspected
  • Electromyography and Nerve Conduction Velocity (EMG/NCV)

Treatment

  • Rest
  • Ice
  • Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)
  • Immobilization
  • Physical Therapy
  • Injection Therapy
  • Custom Orthotic Devices
  • Shoes
  • Bracing
  • Surgery
