A Morton's neuroma is a thickening of the tissue around a nerve leading to the toes. It can be caused by pressure, injury or foot-type. It mostly affects the web in between the third and fourth toes. Patients describe the pain as a pebble in the shoe or a fold in the sock. Some patients may experience a burning sensation or numbness to the ball of the foot or toes.
Treatment might include arch supports and foot pads, corticosteroid injections, strength exercises, wide-toe shoes, or surgery.
