Put simply - Morton's neuroma is a swollen (inflamed) nerve in the ball of the foot, commonly between the base of the second and third toes. Patients experience numbness and pain in the affected area, which is relieved by removing footwear and/or massaging the foot. A neuroma is a tumor that arises in nerve cells, a benign growth of nerve tissue that can develop in various parts of the body. In Morton's neuroma the tissue around one of the nerves leading to the toes thickens, causing a sharp, burning pain in the ball of the foot. A sharp severe pain, often described as a red hot needle may come on suddenly while walking. There may also be numbness, burning and stinging in the toes. Although it is labeled a neuroma, many say it is not a true tumor, but rather a perineural fibroma (fibrous tissue formation around nerve tissue).
The exact cause of Morton?s neuroma is not known, but the choice of footwear seems be a factor. Wearing high heels (shoes with heels over 2 inches) can put extra pressure on the balls of the feet. Wearing tight or pointed toed shoes may squeeze the toes together or otherwise constrict their movement. For that reason, women are about 8 to 10 times more likely to develop Morton?s neuroma compared with men. People who are born with flat feet, high arches, or an abnormal position of the toes are more prone to developing Morton?s neuroma. This may be due to instability around the toe joints. Certain conditions that develop over time, such as bunions or hammer toes, are also associated with Morton?s neuroma. Some sports that involve running, including tennis and other racquet sports, can also increase the chance of developing Morton?s neuroma due to trauma or injury to the foot.
Typically, there's no outward sign of this condition, such as a lump. Instead, you may experience the following symptoms. A feeling as if you're standing on a pebble in your shoe. A burning pain in the ball of your foot that may radiate into your toes. Tingling or numbness in your toes. It's best not to ignore any foot pain that lasts longer than a few days. See your doctor if you experience a burning pain in the ball of your foot that's not improving, despite changing your footwear and modifying activities that may cause stress to your foot.
Your doctor will suspect that you have a Morton's neuroma based on the nature and location of your foot pain. He or she may ask questions about your shoes - what type of shoes you usually wear and whether these shoes have narrow toes or high heels. To rule out other causes of foot pain, your doctor may ask questions about your medical history, especially any history of arthritis, nerve and muscle problems or previous injury to your foot or leg.
Non Surgical Treatment
Simple treatments may be all that are needed for some people with a Morton's neuroma. They include the following. Footwear adjustments including avoidance of high-heeled and narrow shoes and having special orthotic pads and devices fitted into your shoes. Calf-stretching exercises may also be taught to help relieve the pressure on your foot. Steroid or local anaesthetic injections (or a combination of both) into the affected area of the foot may be needed if the simple footwear changes do not fully relieve symptoms. However, the footwear modification measures should still be continued. Sclerosant injections involve the injection of alcohol and local anaesthetic into the affected nerve under the guidance of an ultrasound scan. Some studies have shown this to be as effective as surgery.
For those who are suffering severely with Morton?s Neuroma, surgery is a possibility. An orthopedic surgeon can remove the growth and repair your foot relatively easily. However, Morton?s Neuroma surgery is associated with a lengthy recovery time and there is a possibility that the neuroma may return.
