Tarsal Tunnel Syndrome

A condition that occurs when the tibial nerve is damaged or compressed. The tibial nerve is an ankle nerve. It passes through your tarsal tunnel, a bone and ligament-filled passageway in your ankle.

TTS patients may experience pain, tingling, numbness, or weakness in their feet. TTS may develop as a result of overuse of your foot and ankle. If you exercise vigorously or frequently, especially if you have a very flat foot, you are more likely to develop TTS.


Tarsal tunnel syndrome occurs when your tibial nerve is injured. Tibial nerve damage can be caused by a variety of factors, including:

  • Flat feet.
  • High arches.
  • Injuries, such as an ankle sprain or fracture.
  • Irregular growths, such as ganglion cysts, bone spurs or varicose veins.
  • Masses such as lipomas or tumors near your tibial nerve.
  • Body-wide (systemic) conditions, such as hypothyroidism, diabetes or arthritis.
