Tarsal tunnel syndrome is caused by compression of the posterior tibial nerve as it passes through the tarsal tunnel, which is a narrow space on the inside of the ankle. This nerve entrapment can result overuse, injury, inflammation, or structural abnormalities, such as flat feet or varicose veins. Symptoms of tarsal tunnel syndrome include tingling, burning, or shooting pain in the foot and ankle, numbness, and a feeling of electric shocks radiating into the sole. These symptoms often worsen with prolonged standing or walking. Diagnosis involves a physical examination, focusing on the areas of pain and nerve compression, in addition to imaging studies like MRI scans or ultrasounds to identify underlying causes. Nerve conduction studies may also be used to assess the function of the posterior tibial nerve. Relief options include rest, anti-inflammatory medications, and exercises to alleviate symptoms. Orthotic devices can help reduce pressure on the nerve, and in severe cases, surgical intervention may be necessary. Complications from untreated tarsal tunnel syndrome can lead to chronic pain and permanent nerve damage. If you have pain in this part of your foot, it is suggested that you schedule an appointment with a podiatrist for a precise diagnosis and individualized treatment plan.

Tarsal Tunnel Syndrome

Tarsal tunnel syndrome, which can also be called tibial nerve dysfunction, is an uncommon condition of misfiring peripheral nerves in the foot. The tibial nerve is the peripheral nerve in the leg responsible for sensation and movement of the foot and calf muscles. In tarsal tunnel syndrome, the tibial nerve is damaged, causing problems with movement and feeling in the foot of the affected leg.

Common Cause of Tarsal Tunnel Syndrome

• Involves pressure or an injury, direct pressure on the tibial nerve for an extended period of time, sometimes caused by other body structures close by or near the knee.
• Diseases that damage nerves, including diabetes, may cause tarsal tunnel syndrome.
• At times, tarsal tunnel syndrome can appear without an obvious cause in some cases.

The Effects of Tarsal Tunnel Syndrome

• Different sensations, an afflicted person may experience pain, tingling, burning or other unusual sensations in the foot of the affected leg.
• The foot muscles, toes and ankle become weaker, and curling your toes or flexing your foot can become difficult.
• If condition worsens, infections and ulcers may develop on the foot that is experiencing the syndrome.

A physical exam of the leg can help identify the presence of tarsal tunnel syndrome. Medical tests, such as a nerve biopsy, are also used to diagnose the condition. Patients may receive physical therapy and prescriptive medication. In extreme cases, some may require surgery.
