The ball of your foot is the bottom part just behind your toes. Bands of tissue (ligaments) connect the bones in the ball of your foot. Nerves run between the bones and underneath the ligaments. When a nerve becomes pinched, this causes it to swell and become painful due to the thickening of the tissue that surrounds the nerve. The painful, swollen nerve is called a neuroma (also called Morton's neuroma).
Wearing tight or high-heeled shoes can cause a neuroma. Shoes that are too narrow or too pointed squeeze the bones in the ball of the foot. Shoes with high heels put extra pressure on the ends of the bones. When the bones are squeezed together, they pinch the nerve that runs between them.
The most common symptom of a neuroma is pain in the ball of the foot between two toes. The pain may be dull or sharp. It may feel as if you have a stone in your shoe. You may also have tingling or numbness in one or both of the toes. Symptoms may occur after you have been walking or standing for a while. Taking off your shoes and rubbing the ball of your foot may decrease or relieve the pain.
To prevent a future neuroma, buy shoes with plenty of room across the ball of the foot and in the toes. This keeps the bones from being squeezed together. Wearing low-heeled shoes (less than 2 inches) also puts less pressure on the bones and nerves in the ball of the foot.
