Tarsal tunnel syndrome (TTS), also known as posterior tibial neuralgia, is a compression neuropathy and painful foot condition in which the tibial nerve is compressed as it travels through the tarsal tunnel. This tunnel is found along the inner leg behind the medial malleolus (bump on the inside of the ankle). Patients with TTS typically complain of numbness in the foot radiating to the big toe and the first 3 toes, pain, burning, electrical sensations, and tingling over the base of the foot and the heel. Ankle pain is also present in patients who have high level entrapments. Inflammation or swelling can occur within this tunnel for a number of reasons


  • Pain and tingling in and around ankles and sometimes in toes

  • Swelling of the feet

  • Painful burning, tingling, or numb sensations in the lower legs. Pain worsens and spreads after standing for long periods; pain is worse with activity and is relieved by rest.

  • Electric shock sensations

  • Pain radiating up into the leg, and down into the arch, heel, and toes

  • Hot and cold sensations in the feet

  • A feeling as though the feet do not have enough padding

  • Pain while operating automobiles

  • Pain along the Posterior Tibial nerve path

  • Burning sensation on the bottom of foot that radiates upward reaching the knee

  • “Pins and needles”- type feeling and increased sensation on the feet
