Definition

A neuroma is a noncancerous (benign) growth of nerve tissue that can develop in various parts of your body. Morton's neuroma occurs in a nerve in your foot, often between your third and fourth toes. The condition involves a thickening of the tissue around one of the nerves leading to your toes. Morton's neuroma causes a sharp, burning pain in the ball of your foot. Your toes also may sting, burn or feel numb.

Also called plantar neuroma or intermetatarsal neuroma, Morton's neuroma may occur in response to irritation, injury or pressure. Morton's neuroma may also occur for unknown reasons.

Common treatments for Morton's neuroma include changing footwear or using arch supports. Sometimes, corticosteroid injections or surgery may be necessary.
