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.
