What is tarsal tunnel syndrome?
Carpal tunnel syndrome is an often well understood condition of the wrist. The foot and ankle have a similar, less common condition called Tarsal Tunnel Syndrome. The tarsal tunnel is a tight space in the foot that lies between bones and tough fibrous tissue extending from the ankle into the foot. A nerve called the posterior tibial nerve lies within the tarsal tunnel. If this nerve becomes compressed or squeezed, tarsal tunnel syndrome can result. Some common causes of compression can include constriction of the space, injury to the surrounding tissues, injury to the nerve, artery or vein problems (including varicose veins), or masses in the area. Symptoms include numbness over the bottom of the foot and/or pain, burning and tingling over the base of the foot and heel. Often these symptoms can be quite severe and treatment should be considered.
