Maybe you've heard of carpal tunnel syndrome, a condition in the wrist that occurs when swelling or a change in position of the tissue within the carpal tunnel squeezes and irritates the median nerve. Similar to carpal tunnel syndrome is tarsal tunnel syndrome, an ankle condition that occurs from the compression of a nerve in a confined space.
What is Tarsal Tunnel Syndrome?
The tarsal tunnel is a narrow space located on the inside of the ankle next to the ankle bones. Protected by the tarsal tunnel are many arteries, veins, tendons and nerves, one of which is the posterior tibial nerve - the main focus of tarsal tunnel syndrome.
Tarsal tunnel syndrome is caused from a compression on the posterior tibial nerve. Causes include:
- Injury to the ankle, which may produce swelling near the nerve.
- Abnormal blood vessels or cysts that occupy space within the tunnel.
- Scar tissue that press against the nerve.
- Foot deformities, such as flat feet, which increase strain on the nerve.
- Systematic diseases, such as diabetes or arthritis.
When patients visit us at our office with tarsal tunnel syndrome, they often experience one or more symptoms, usually felt on the bottom of the foot or the inside of the ankle. In some cases, the pain may extend to the heel, arch, toes and calf. Symptoms include:
- Burning or tingling sensation
We Can Help
If you experience pain, burning and tingling in your feet or toes, make an appointment with our office. Left untreated, tarsal tunnel syndrome could result in permanent nerve damage. Treatment for tarsal tunnel syndrome varies depending on the severity of your condition. Anti-inflammatory medications, cortisone injections, immobilization, rest and modifications in footwear are a few methods used to treat the damaged nerve and reduce the pain. When non-surgical treatments are unsuccessful, surgery may be recommended.
A neuroma is a thickening of nerve tissue that can develop in various parts of your body. In the foot, the most common occurring neuroma develops at the base of the third and fourth toes. This condition is referred to as Morton's neuroma.
There are typically no physical signs of Morton's neuroma, such as a lump or a knot. Instead, symptoms may include:
- A sharp, achy or burning pain in the ball of your foot
- Numbness, tingling, or cramping in the toes or forefoot
- Feeling as if you're standing on a pebble in your shoe
While the exact cause of Morton's neuroma is unknown, the growth of the neuroma seems to occur in response to injury, pressure or irritation to one of the nerves that lead to the toes. People with foot deformities such as bunions, hammertoes and flat feet are at higher risk for developing a neuroma. Women are also more likely to develop this condition, as wearing high-heels or narrow-toed shoes can increase pressure on the toes. Other potential causes are activities that involve repetitive irritation to the ball of the foot, such as running.
Morton's neuroma can make walking and performing normal activities difficult and painful. Treatment options vary with severity, and identifying the neuroma in its earliest stage of development is important to avoid more invasive treatments or surgical correction. Left untreated, neuromas tend to worsen, so it's always best to visit our office at the first sign of pain.
Early treatments aim to relieve or reduce pressure on the area around the affected toes. Depending on the severity of your neuroma, a podiatrist may recommend:
- Modifications to footwear. Wide-toed shoes relieve pressure on the neuroma.
- Shoe inserts or padding to provide support for the arch of the foot, which removes pressure from the nerve.
- Anti-inflammatory medications can help ease any pain and inflammation. Ask your doctor first.
- Icing to reduce inflammation.
- Rest to lessen repetitive pressure on the neuroma.
In the most severe cases, surgery may be recommended for patients who do not respond to conservative treatments. We can help you determine the best approach for your specific condition.
