Neuromas

A neuroma is a benign swelling of a nerve that is secondary to trauma or compression. If the swelling of the nerve is chronic, then permanent nerve damage can occur. A very common area for a neuroma to occur is in the ball of the foot.

Neuromas are usually occur due to compression between the metatarsal bones, which are long bones located just behind the toes. Nerves course between the metatarsal bones to provide sensation to the toes. At the base of the digits, the nerve splits into a Y shape and enters the toes. Where the nerve splits into a Y is usually where the nerve gets pinched, causing swelling and ultimately the neuroma. A neuroma can manifest as burning pain, tingling and numbness. It has been shown that by removing the shoe and rubbing the foot, symptoms can be alleviated.

As the nerve continues to swell and become larger, the nerve can create a clicking or poppnig sensation when walking as it moves between the metatarsal bone. The neuroma pain comes and goes and is further aggravated by pinching of the nerve.

The most common region of the foot to develop a neuroma is between the 3rd and 4th toes, but also between the 2nd and 3rd toes. Neuromas can occur in both feet or just one foot.

Neuromas are diagnosed by a thorough history and physical exam. Neuromas can often be mistaken for arthritis, stress fractures, avascular necrosis, capsulitis, etc.  X-rays are taken to rule out the previously mentioned problems. X-rays do not show neuromas. Sometimes, special exams such as MRI or nerve conduction studies must be performed to help with the diagnosis.

Treat for neuromas usually consistent of one if not several of the following:

1. Corticosteroid injections

2. Orthotics

3. Chemical destruction of the nerve

4. Surgery
