Tarsal tunnel syndrome occurs when the posterior tibial nerve is compressed as it passes through the tarsal tunnel, a narrow channel located on the inside of the ankle. This compression often results in pain, tingling, or burning sensations along the inner ankle, sometimes extending to the toes. Symptoms can worsen with prolonged standing or walking, and may be experienced even at rest. Factors that can contribute to tarsal tunnel syndrome include abnormal foot mechanics, inflammatory conditions like rheumatoid arthritis, or the presence of cysts. A chiropodist can recommend orthotics to stabilize the foot and reduce pressure on the affected nerve. They may also suggest footwear modifications and provide supportive taping techniques to alleviate nerve tension. In more persistent cases, advanced imaging may be needed. If you are experiencing pain on the inner side of your ankle, it is suggested that you schedule an appointment with a chiropodist for guidance.

Tarsal tunnel syndrome can cause pain and progress over time. If you are experiencing any symptoms of tarsal tunnel syndrome, please consult with Cynthia Chan, B.Sc., D.Ch from Healthy Advantage Foot & Orthotic Clinic. Our practitioner will assess your condition and provide you with quality foot and ankle treatment. 

What Is Tarsal Tunnel Syndrome?

Tarsal tunnel syndrome is a condition in which the posterior tibial nerve, which is located within a structure called the tarsal tunnel on the inside of the ankle, is squeezed. Compression of the posterior tibial nerve can be caused by injuries, such as ankle sprains, systemic diseases like diabetes or arthritis, strain on the tarsal tunnel due to flat feet, or an enlarged structure like a cyst squeezing the nerve. 

Symptoms

Symptoms of tarsal tunnel syndrome can appear suddenly and are generally worsened by physical activity. 

Common symptoms include: 

• Tingling, burning, or electrical shock sensation on the inside of the ankle or bottom of the foot

• Numbness

• Shooting pain 

Diagnosis

Tarsal tunnel syndrome is diagnosed through physical examination. If initial treatment is ineffective, imaging or nerve studies may also be necessary. 

Treatment

Nonsurgical treatments for tarsal tunnel syndrome include resting and icing the foot, bracing or immobilizing the foot, wearing an orthotic device, modifying your footwear, and taking medications to relieve pain. Surgery may be needed if nonsurgical treatments are ineffective.
