Morton’s neuroma is a painful condition that primarily affects the ball of the foot and/or the area between the third and fourth toes. It may feel as though you are standing with a pebble in your shoe, or even a fold in your sock.
It is caused by a thickening of the tissue around one of the nerves leading into the toe. Morton’s neuroma symptoms can cause a sharp, painful sensation in the ball of the foot which can be accompanied by tingling, numbness, or burning. Usually, there is no external indication of the injury – it is often symptom-based.
