Tarsal Tunnel Syndrome is a painful foot condition caused when the tibial nerve which provides sensation to the bottom of the foot, becomes compressed. The tibial nerve, artery and tendons together run through the tarsal tunnel found along the inner leg behind the bump on the inside of the ankle. They provide the movement and flexibility to the foot.
When the tarsal nerve is compressed, it causes pain, a burning sensation and tingling on the sole of the foot, in and around the ankles and sometimes the toes. Tarsal tunnel syndrome may be caused by an injury or disease, or can be due to the natural shaping of the foot. For example, flat feet, fallen arches or swelling caused by an ankle sprain can cause tarsal tunnel syndrome.
Tarsal tunnel syndrome can be treated with corticosteroid and anesthetic injections.
