If you suffer from sharp foot pain, please Schedule an appointment with one of our orthopedic specialists as soon as possible.

What is Tarsal Tunnel Syndrome?

model image of tarsal tunnel in foot Tarsal tunnel syndrome occurs when compression or irritation affects the posterior tibial nerve within the tarsal tunnel, a narrow passage located along the inner side of the ankle. The tunnel contains the posterior tibial nerve, blood vessels, and tendons that travel from the lower leg into the foot. Pressure within this confined space can interfere with normal nerve function.

Tarsal tunnel syndrome refers specifically to dysfunction involving the posterior tibial nerve as the nerve passes through this passage. The condition belongs to a group of nerve compression disorders and shares similarities with carpal tunnel syndrome in the wrist. The term describes the location and nature of the nerve problem rather than a specific underlying cause.

Causes of Tarsal Tunnel Syndrome

Tarsal tunnel syndrome can develop when conditions around the inner ankle place pressure on the posterior tibial nerve. Several injuries, structural changes, and medical conditions can narrow the tarsal tunnel or increase pressure within the space.

Causes may include:

Ankle sprains or fractures
Flat feet or fallen arches
Swelling around the ankle
Arthritis
Tendon inflammation
Varicose veins
Cysts or tumors near the tarsal tunnel
Bone spurs
Scar tissue following an injury or surgery
Diabetes and other conditions that affect nerve health

Symptoms of Tarsal Tunnel Syndrome

Tarsal tunnel syndrome can cause sensations that affect the ankle, heel, and bottom of the foot. Symptoms may develop gradually and often become more noticeable after standing, walking, or other activities that place pressure on the foot.

Symptoms may include:

Burning pain along the inner ankle or foot
Tingling in the bottom of the foot
Numbness in the heel or sole
Shooting or electric-like pain
Increased pain after prolonged standing
Pain that worsens during physical activity
Weakness in the foot or ankle

Treatment Options for Tarsal Tunnel Syndrome

For mild cases of tarsal tunnel syndrome, doctors often recommend conservative treatments that reduce pressure on the posterior tibial nerve and support proper foot function. Treatment may include rest, activity modification, ice, supportive footwear, arch supports, custom orthotics, physical therapy, stretching exercises, and anti-inflammatory medications. Bracing may also help stabilize the ankle and reduce strain on the affected area.

For severe cases, doctors may consider more advanced treatments when conservative approaches fail to provide adequate relief. Corticosteroid injections can help reduce inflammation around the nerve, while treatment for underlying foot or ankle problems can address contributing factors. Tarsal tunnel release surgery can relieve pressure on the posterior tibial nerve when persistent compression requires surgical treatment.
