Morton's Neuroma Running

Introduction


The term neuroma refers to a swelling of a nerve. The nerve commonly affected is a small nerve that connects the 3rd and 4th toes, counting from the big toe. The patient will complain of pain in the sole of the foot.

Symptoms of Mortons Neuroma


*Begins with numbness or tenderness in the foot, just behind the 3rd and 4th toes
*At a later stage, pain, numbness, burning and tingling sensations can radiate around the foot.
*The symptoms may appear and disappear spontaneously.
*Severe pain may be present at weight bearing.
*The patient may experience spontaneous shooting pains, which are often referred to as an "electric shock". This can affect patients when they are sleeping at night.

 


Causes of Mortons Neuroma


The pulling of the ligaments under the foot irritates the nerve.
High heels can damage the nerve.

A tight toe box will squeeze the toes in the foot and therefore put pressure on the nerve.

Mechanical problems with the feet such as "over pronation". Over pronation can be simply described as a condition, which causes your arches to flatten out when you stand up. This causes your ankles to roll in towards each other and disturbs your normal walking pattern. If a foot over pronates the structures of the foot are put under stress, which increases the likelihood of a neuroma occurring.


Treatment of Mortons Neuroma


I have found that patients respond well to sports insoles with the addition of silicone padding under the forefoot area. A review of running shoes may also be necessary.
