The tarsal tunnel is located on the inside of the ankle and contains the posterior tibial nerve. Tarsal Tunnel Syndrome occurs when the posterior tibial nerve is compressed resulting in shooting pain, tingling, and burning on the inside of the ankle radiating to the bottom of the foot.
Tarsal tunnel syndrome can be caused by anything that causes compression of the posterior tibial nerve. The inward rolling of the foot associated with flat feet is a common cause. Individuals with Tarsal Tunnel Syndrome as a result of flat feet may benefit from Orthotics by Orthodynamics in conjunction with a stability shoe. This combination will limit the inward rotation of the foot which will decrease pressure on the nerve.
Swelling of the ankle associated with an acute injury such as an ankle sprain can also result in compression of the posterior tibial nerve. Treatment in this instance will often consist of rest, ice, elevation, and immobilization. A Cam Walker by Ovation is often used to immobilize the foot and ankle allowing the nerve and surrounding structures to heal.
