Morton's Neuroma Diagnosis

Morton’s neuromas are a source of pain or discomfort for those affected by them. A neuroma is caused by the compression of inflammation of the nerves. Morton’s neuromas are a thickening of the nerves of the third and fourth toes.

The Morton’s neuroma can cause pain, burning, and tingling in the foot. It may cause a sensation that there is a pebble inside the ball of the foot. The pain becomes progressively worse over time. A Morton’s neuroma can lead to permanent nerve damage if left untreated.

The pain from a Morton’s neuroma often becomes worse while walking, exercising, or wearing shoes. Because Morton’s neuromas are caused by compression to the nerves, they more commonly affect women. This is due to ill-fitting women’s shoes and high heels. Shoes that are too narrow or have pointed toes exert too much pressure on the foot. Morton’s neuromas are only one of several foot disorders that can be attributed to such footwear.

A Morton’s neuroma must be diagnosed by a physician. A doctor will take a thorough history of the onset of the symptoms. An x-ray may be taken to rule out the presence of a fracture. An x-ray can also rule out arthritis by using it to judge bone density.

A podiatrist may be able to feel the neuroma by squeezing and pushing on the affected area. The podiatrist may look for Mulder’s sign. Mulder’s sign is the occurrence of a clicking noise when the foot is squeezed with one hand while pressure is exerted on the affected area by the podiatrist’s other hand.

An MRI (magnetic resonance imaging) scan might be used to check to make sure the compression of the nerve is not caused by a tumor. The MRI can be used to judge the lsize of the neuroma and its progression. This helps the doctor determine the best course of treatment.
