The tarsal tunnel is a dense band of fibrous tissue which holds the tibial nerve and arteries, running along the inner leg and behind the bump on the inside of the ankle.
What causes Tarsal Tunnel Syndrome?
There is no one specific cause for tarsal tunnel syndrome, but inflammation is the most recognized reason for TTS. Since the tibial nerve is encased in the tarsal tunnel, anything that takes up extra room, like inflammation, causes swelling in the tissues and puts pressure on the nerve. When the nerve becomes "pinched", it sends a pain signal, which may be felt anywhere from the toes through the lower leg, depending on where the nerve is under pressure. Inflammation can be caused by varicose veins, a noncancerous tumor on the nerve, trauma, edema, arthritis, ankle sprain, flat feet, bone spur, ganglion cyst, or any number of conditions.
Symptoms of Tarsal Tunnel Syndrome may include :
