What is a neuroma?

A neuroma is a generalized term for an enlarged nerve within the body. They can occur on any nerve in the body, however, they are most commonly found in the feet, and hands.

 

Although neuroma sounds like a tumor such as a melanoma, lymphoma or carcinoma, they are not cancerous. It is actually perineural fibrosis, or fibrous tissue that is enlarged around a nerve. The most common type of neuromas are found in the feet, and they are called Morton’s neuroma. A Morton’s neuroma is an enlarged, painful nerve in the ball of the foot.

A Morton’s neuroma usually occurs between the third and fourth toes, or less commonly between second and third toes. They occur on the common metatarsal nerve. It is more common in females than males

Why is it called a Morton’s neuroma?

Morton’s Neuroma was named after Thomas George Morton who, ironically and erroneously, described it as a painful condition related to the fourth metatarsal phalangeal joint. It was correctly described by Dr. Lewis Durlacher.

What are the symptoms of a Morton’s neuroma?

The symptoms of Morton’s neuroma vary from patient to patient. Commonly, patients describe:

 

·       Numbness or tingling in two adjacent toes

·       Pain between two adjacent toes

·       Pain in the ball of the foot

·       Burning sensation in the foot or toes

·       Feeling a pebble in the sock

·       A ball or bunched-up piece of fabric in the sock

·       Shooting or electrical shock in the foot or toes

 

Neuroma symptoms are often intermittent but may also be constant. They are often increased with increased activity or certain shoe types. Particularly, tight shoes may cause increased symptoms.
