Tarsal tunnel syndrome develops when the posterior tibial nerve becomes compressed within a narrow passage near the inside of the ankle, called the tarsal tunnel. This nerve travels through the ankle and supplies areas of the heel and bottom of the foot. When pressure develops around the nerve, pain can occur along its path. Several problems may contribute to this compression. Abnormal foot function, inflammatory arthritis, and ankle swelling are possible factors. Cysts or changes in the tissues surrounding the nerve may also reduce space within the tunnel and create irritation.
Symptoms of tarsal tunnel syndrome commonly include pain around the inside of the ankle. The discomfort may spread into the heel, sole, or toes. Some people describe the pain as burning or tingling. Symptoms often become worse while standing or walking. As nerve compression progresses, discomfort may eventually occur even while resting. Because heel and arch pain can have several possible causes, determining where the symptoms begin and how they spread is important. A professional examination can help distinguish tarsal tunnel syndrome from other foot problems that may cause similar discomfort.
A podiatrist can evaluate foot and ankle pain to determine whether the posterior tibial nerve may be compressed. During an examination, pressure or tapping near the affected nerve may reproduce tingling that travels toward the heel or toes. Nerve testing may help support a diagnosis, while an MRI can identify a growth or other structure placing pressure on the nerve. Treatment depends on the underlying cause and severity of the symptoms. Professional options may include orthotics or injections to reduce symptoms. Surgery may be necessary when persistent nerve compression does not respond to other treatments. If burning, tingling, or persistent pain is affecting your ankle or foot, it is suggested that you consult a podiatrist for an evaluation and appropriate treatment options.
Tarsal tunnel syndrome can be very uncomfortable to live with. If you are experiencing tarsal tunnel syndrome, contact Dr. Anna Petrov of Family Foot & Ankle Care. Our doctor can provide the care you need to keep you pain-free and on your feet.
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.
