Neuromas

A neuroma is the swelling of nerve that is a result of a compression or trauma. They are often described as nerve tumors. However, they are not a tumor in the purest sense . They are a swelling within the nerve that may result in permanent nerve damage. The most common site for a neuroma is on the ball of the foot. The most common cause of neuroma in that area is the abnormal movement of the long bones behind the toes called metatarsal bones. A small nerve passes between the spaces of the metatarsals. At the base of the toes, the nerves split forming a “Y” and enter the toes. It is in this area the nerve gets pinched and swells, forming the neuroma.

Burning pain, tingling, and numbness in one or two of the toes is a common symptom. Sometimes this pain can become so severe, it can bring tears to a patient’s eyes. Removing the shoe and rubbing the ball of the foot helps to ease the pain. As the nerve swells, it can be felt as a popping sensation when walking. Pain is intermittent and is aggravated by anything that results in further pinching of the nerve. When the neuroma is present in the space between the third and fourth toes, it is called a Morton’s Neuroma. This is the most common area for a neuroma to form. Another common area is between the second and third toes. Neuromas can occur in one or both of these areas and in one or both feet at the same time. Neuromas are very rare in the spaces between the big toe and second toe, and between the fourth and fifth toes. Neuromas have been identified in the heel area, resulting in heel pain.
