A neuroma is a thickening of nerve tissue that can develop in various parts of the body, creating nerve damage. Morton’s neuroma is the most common neuroma in the foot. It occurs at the base of the third and fourth toes.

Symptoms of Morton’s Neuroma

If you have a Morton’s neuroma, you will likely experience the following symptoms:

• Tingling
• Burning
• Numbness
• Pain
• A feeling that something is inside the ball of the foot

The symptoms begin gradually and occur only occasionally at first. This generally happens when wearing narrow‐toed shoes or performing certain aggravating activities. The symptoms may go away temporarily by massaging the foot or by avoiding activities that brought on the pain

However, over time, the symptoms progressively worsen and may persist for several days or weeks at a time. The symptoms become more intense as the neuroma grows in size and the nerve damage becomes more permanent.

One risk factor is wearing shoes that have a tapered toe box, or high‐heeled shoes that cause the toes to be forced into the toe box. People with foot deformities such as bunions, hammertoes, or flatfeet are at high risk for developing a neuroma. So are those who participate in activities that require a repetitive irritation to the ball of the foot, such as running or racquet sports.
