What is tarsal tunnel? how is it treated?

Pressure on a nerve: Tarsal tunnel syndrome can be treated conservatively with injections around the problem area, physical therapy to strengthen and improve the function of the ankle, and splinting to hold the ankle off the nerve that is getting pinched. If these things do no work quickly, though, an orthopedic surgeon may need to do surgery to relieve the compression on the nerve.

It is a compression: Neuropathy of the posterior tibial nerve or one of its branches by the inner ankle. Treatments include orthotics to realign the foot and take reassure off the nerve, sometimes injections, sometimes surgery to decompress the nerve.
