This condition is caused by a thickening of the nerve that runs between any two toes either by trauma or as a result of an abnormality of the foot. Neuromas most often in the ball of the foot, causing a pinched and inflamed nerve.
What is a neuroma?
Neuromas—enlarged benign growths of nerves, most commonly between the third and fourth toes. Neuromas are caused by tissue rubbing against and irritating the nerves. Pressure from ill-fitting shoes or abnormal bone structure can also lead to this condition.
Treatment: Depending on the severity, treatments may include orthotics (shoe inserts), cortisone injections, and, in extreme cases, surgical removal of the growth.
During neuroma procedures, an incision is made on the top of the foot in the location of the neuroma, usually between the second and third toes or between the third and fourth toes. After the nerve is located, the surgeon cuts and removes it.
