What causes tarsal tunnel syndrome?

Tarsal tunnel syndrome refers to pain, numbness, and tingling in your foot due to a pinched nerve. It involves the posterior tibial nerve—the one that runs along the inside of your ankle—which could be compressed in several ways.

The tarsal tunnel is formed by bone and a ligament sheath on the inside of your ankle. The posterior tibial nerve runs through this tunnel. It can be pinched when a bone or tendon presses on it. People with flat feet are more prone to this condition because their ankles often tilt out of position. A tumor, cyst, bone spur, or swollen tendon can pressure the nerve as well. Diseases like arthritis or an injury like a sprain can cause problems because of general swelling in the ankle, too.

If you experience pain, numbness, or tingling in your ankle, or down into your foot and toes, don’t wait to have it tended to.
