Tarsal tunnel syndrome is pain in the ankle, foot, and sometimes toes caused by compression of or damage to the nerve supplying the heel and sole (posterior tibial nerve).

  • Symptoms include burning or tingling pain that occurs when people walk or wear certain shoes.

  • The diagnosis is based on an examination of the foot and nerve conduction studies.

  • Corticosteroid injections, orthoses, and sometimes surgery are needed to relieve the pain.

The posterior tibial nerve runs down the back of the calf, through a fibrous canal (tarsal tunnel) near the heel, and into the sole of the foot. When tissues around the tarsal tunnel become inflamed, they can swell and press on the nerve (nerve compression), causing pain.

Disorders that can cause or contribute to tarsal tunnel syndrome include fracture, ankle swelling caused by heart failure Heart Failure (HF) Heart failure is a disorder in which the heart is unable to keep up with the demands of the body, leading to reduced blood flow, back-up (congestion) of blood in the veins and lungs, and/or... read more Heart Failure (HF) or kidney failure Overview of Kidney Failure Kidney failure is the inability of the kidneys to adequately filter metabolic waste products from the blood.

Poor foot posture may also contribute if the ankle rolls too far inward and stresses the nerve within the tarsal tunnel.

Symptoms of Tarsal Tunnel Syndrome

Pain, the most common symptom of tarsal tunnel syndrome, usually has a burning or tingling quality that may occur when a person stands, walks, or wears a particular type of shoe. Pain located around the ankle (usually on the inner side) and extending to the toes usually worsens during walking and is relieved by rest. As the disorder progresses, pain also may occur during rest.

Diagnosis of Tarsal Tunnel Syndrome

  • A doctor's examination of the foot

  • Sometimes nerve conduction studies

To diagnose tarsal tunnel syndrome, a doctor manipulates the affected foot during a physical examination. For example, tapping the injured or compressed area just below the ankle bone often causes tingling (referred to as the Tinel sign), which may extend to the heel, arch, or toes.

Treatment of Tarsal Tunnel Syndrome

  • Corticosteroid injections

  • Orthoses

  • Sometimes surgery

Other treatments include wrapping the foot and placing specially constructed devices in the shoe (orthoses).

When other treatments do not relieve the pain, surgery to relieve pressure on the nerve may be necessary.
