A neuroma is a swelling or scarring of a small nerve that connects to two of your toes and provides sensation to these toes. The symptoms can come and go depending on activity, shoe style and even, weather. They consist of pain or numbness, usually affecting the 3rd and 4th toes, counting from the big toe. Any action that shifts the body weight onto the front of the foot, such as wearing high heels, climbing stairs and running, can make a neuroma worse. Some doctors will describe a neuroma as a nerve tumor. However, don’t worry because neuromas are not cancer and will not spread to other parts of your body. It is an injury to a nerve, that occurs slowly, over a long period of time.
