Morton's neuroma is a painful condition that affects the ball of your foot, most commonly the area between your third and fourth toes. Morton's neuroma may feel as if you are standing on a pebble in your shoe or on a fold in your sock. Morton's neuroma involves a thickening of the tissue around one of the nerves leading to your toes. This can cause a sharp, burning pain in the ball of your foot. Your toes also may sting, burn or feel numb. High-heeled shoes have been linked to the development of Morton's neuroma. Many people experience relief by switching to lower heeled shoes with wider toe boxes. Sometimes corticosteroid injections or surgery may be necessary.
The exact cause is as yet unclear. However there are a number of theories. Some expert s believe problems with the design of the foot makes some people more prone to Morton?s neuroma. Having flat feet or a high arch for example encourages the foot to slide forwards which can put excess pressure on the metatarsals. Bunions and hammer toes also increase the likelihood of developing Morton?s. However simply wearing high heels or any form of tight shoes that put pressure on the bones in the feet can also lead to a Morton?s . Typically the condition comes on between the age of 40 and 50. It is far more common in women than men - three out of four sufferers are women.
Morton's neuroma may cause Burning, pain, tingling, and numbness often shooting into the toes. Discomfort that is worse while walking. Feeling of a lump between the toes. Symptoms are usually temporarily relieved when taking off shoes, flexing toes or rubbing feet.
Plain x-rays of the foot may demonstrate that one or more of the metatarsals are long (Figure #5). Not uncommonly, the second and/or third metatarsal may be long relative to the third or fourth. This can create a situation where excessive load is occurring in and around the vicinity of the interdigital nerve.
Non Surgical Treatment
If your Morton's neuroma is painful, your doctor usually will begin treatment with conservative therapies, including a switch to shoes with low heels, wide toes and good arch support. Padding techniques, including metatarsal pads or toe crest pads. Shoe inserts (orthotics) to help correct any mechanical imbalance in the foot. Anti-inflammatory medication, such as ibuprofen (Advil, Motrin and other brand names) or naproxen (Aleve, Naprosyn and other brand names) A local injection of anesthetic and corticosteroid medication into the affected area. Inflamed or injured nerves can take months to improve, even after the underlying problem has been corrected.
If conservative treatments haven't helped, your doctor might suggest injections. Some people are helped by the injection of steroids into the painful area. In some cases, surgeons can relieve the pressure on the nerve by cutting nearby structures, such as the ligament that binds together some of the bones in the front of the foot. Surgical removal of the growth may be necessary if other treatments fail to provide pain relief. Although surgery is usually successful, the procedure can result in permanent numbness in the affected toes.
