Tarsal Tunnel Syndrome

The tarsal tunnel is a tight space in the foot that lies between bones and tough fibrous tissue. A nerve called the posterior tibial nerve lies within the tarsal tunnel. If this nerve becomes compressed or squeezed, tarsal tunnel syndrome can result. Symptoms include numbness over the bottom of the foot and/or pain, burning and tingling over the base of the foot and heel. Tarsal tunnel syndrome is similar to carpal tunnel syndrome, which occurs in the wrist. Both disorders arise from the compression of a nerve in a confined space.
