In the foot, a neuroma is a nerve that becomes irritated and swells up. If the nerve stays irritated, it can become thickened which makes the nerve larger and causes more irritation. Pain from a neuroma is usually felt on the ball of your foot. Corns and calluses are areas of thick, hard skin. They usually develop due to rubbing or irritation over a boney prominence. The hard, thick skin is called a corn if it is on your toe and it is called a callus if it is somewhere else on your foot.
