NEUROMA

NEUROMA

An interdigital neuroma or Morton’s Neuroma is compression and aggravation of the common interdigital nerve. It is located between the metatarsal heads. One theory is overall compression of the forefoot. Side to side, tight shoes, high heeled shoes, soccer shoes, or ski boots, can cause excessive pressure on the interdigital nerve. This pressure can aggravate the nerve and can be very painful. When the nerve becomes irritated, the body tries to protect and the nerve and it becomes covered in a bundle of protective tissue which in turn makes the nerve larger and more sensitive to pressure.

This can sometimes be felt in the forefoot between the metatarsal heads towards the web space and when pressure is applied to the neuroma, the pain is reproduced. Another theory is that the interdigital nerve is irritated by the intermetatarsal ligament. Sometimes this ligament can sag downward toward the nerve, thus the transmetatarsal arch decreases which compresses the nerve. The entrapped and damaged nerve can cause aching and burning in the forefoot. Pain, numbness, or an electrical shock sensation is also common on the toes. The foot usually feels better without the shoe on. 

 If you think you suffer from this condition please contact a medical specialist.
