Morton’s Neuroma (interdigital neuroma)

Definition

Morton’s Neuroma is a common foot problem associated with pain, swelling and/or an inflammation of a nerve, usually at the ball-of-the-foot between the 3rd and 4th toes. Symptoms of this condition include sharp pain, burning, and even a lack of feeling in the affected area. Morton’s Neuroma may also cause numbness, tingling, or cramping in the forefoot.

Cause

• Morton’s Neuroma is a foot condition caused from an abnormal function of the foot that leads to bones squeezing a nerve usually between the 3rd and 4th metatarsal heads. Symptoms of Morton’s Neuroma often occur during or after you have been placing significant pressure on the forefoot area, while walking, standing, jumping, or sprinting. This condition can also be caused by footwear selection. Footwear with pointed toes and/or high heels can also cause the formation of a neuroma. Constricting shoes can pinch the nerve between the toes, causing discomfort and extreme pain.

Treatment and Prevention

The first step in treating Morton’s Neuroma is to select proper footwear. Footwear with a deep and wide toe box (toe area) is ideal for relieving the pain. If our podiatrist has highlighted a structural malalignment of your foot, the use of a Prescription Foot Orthotic is recommended. The orthotic device will correct the malalignment of your foot that is causing the nerve to be pinched and subsequently alleviate your symptoms.
