Tarsal Tunnel Syndrome: Symptoms, Causes, and Treatment Options

Symptoms

Typically affect the medial ankle and plantar foot:

  • Tingling, burning, or electric-shock sensations
  • Numbness along the arch, heel, and sole
  • Shooting pain radiating up the leg
  • Worsening with activity, standing, or at night

Causes

  • Compression of the posterior tibial nerve in the tarsal tunnel (behind medial malleolus)
  • Causes: flat feet, ankle sprain, ganglion cyst, varicose veins, tenosynovitis, diabetes, arthritis

Treatment

  • Conservative: Rest, ice, NSAIDs, orthotics (arch support), immobilization, physical therapy
  • Injections: Corticosteroid into tarsal tunnel
  • Surgery: Tarsal tunnel release (decompression) if conservative fails

Early diagnosis improves outcomes. See a podiatrist or orthopedist for persistent foot nerve symptoms.
