Causes
Unfortunately, the cause of Morton?s Neuroma remains unknown to researchers. It is likely that a variety of factors may play a role in the development of this condition, including the presence of chronic pain conditions like fibromyalgia. Factors that may contribute to the development of Morton?s Neuroma include Wearing improperly fitting shoes can cause pressure on your foot, leading to swelling around the toe nerves. High heels are of particular concern as they cause a large amount of weight to be shifted to the ball of the foot. Repetitive activities like jogging, walking, and aerobics can also place a lot of pressure on the feet. This could lead to Morton?s Neuroma. Having a previous foot or muscle injury may cause you to hold your foot in a poor position when walking, contributing to nerve inflammation. Some people are just born with poorly shaped feet. People with extremely low arches or "flat feet" may suffer from Morton?s Neuroma more than others.
Symptoms
If you have a Morton's neuroma, you will probably have one or more of these symptoms. Tingling, burning, or numbness. A feeling that something is inside the ball of the foot, or your sock is bunched up. Pain that is relieved by removing your shoes. A Morton's Neuroma often develops gradually. At first the symptoms may occur only occasionally, when wearing narrower shoes or performing certain activities. The symptoms may go away temporarily by massaging the foot or by avoiding aggravating shoes or activities. Over time the symptoms progressively worsen and may persist for several days or weeks. The symptoms become more intense as the neuroma enlarges and the temporary changes in the nerve become permanent.
Diagnosis
X-rays of your affected foot will not show a neuroma, as neuromas are made up of soft tissue. X-rays may be helpful, however, in helping rule in osteoarthritis or a stress fracture as the cause of your symptoms. Ultrasonography and MRI are sometimes used to help diagnose neuromas, although they are often ineffective. The clinical diagnosis by a foot care expert with experience treating this health problem is usually the most effective way to diagnose neuromas. Your podiatrist will attempt to duplicate your neuroma symptoms by pressing on the involved nerve at various points, and he or she may try to cause a clicking of your nerve that indicates nerve enlargement.
Non Surgical Treatment
Wearing shoes that provide enough room in the toe box is also the first step in treating Morton?s neuroma. For instant relief when pain flares up, try taking your shoes off and rubbing the area. The nerve can get trapped below the ligament, and rubbing can move it back to its natural position. Your doctor or a foot-care specialist may recommend lower heels and metatarsal pads. These pads provide cushioning under your neuroma and better arch support to redistribute your weight. If you keep pressure off the toes and wear wide enough shoes, the problem may gradually disappear.

Surgical Treatment
When early treatments fail and the neuroma progresses past the threshold for such options, podiatric surgery may become necessary. The procedure, which removes the inflamed and enlarged nerve, can usually be conducted on an outpatient basis, with a recovery time that is often just a few weeks. Your podiatric physician will thoroughly describe the surgical procedures to be used and the results you can expect. Any pain following surgery is easily managed with medications prescribed by your podiatrist.
