Mortons Neuroma Diagnosis

Overview

interdigital neuromaMortons Neuroma is a common painful condition involving compression of nerves between the long bones of the forefoot just before they enter the toes. Commonly this involves the 3rd and 4th toes, however may affect the 2nd and 3rd toes. Repeated trauma or compression of these nerves causes the nerves to swell and thicken causing a Morton’s neuroma to develop.

Causes

Morton’s neuroma may be the result of irritation, pressure or injury. In some cases its cause is unknown. In the majority of cases only one nerve is affected. Having both feet affected is extremely rare. A high percentage of patients with Morton’s neuroma are women who wear high-heeled or narrow shoes. Patients with Morton’s neuroma may need to change their footwear, take painkillers or steroid injections, while others may require surgery to either remove the affected nerve or release the pressure on it.

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

A doctor can usually identify Morton’s neuroma during a physical exam. He or she will squeeze or press on the bottom of your foot or squeeze your toes together to see if it hurts. Your doctor may also order an X-ray of your foot to make sure nothing else is causing the pain.

Non Surgical Treatment

Nonsurgical treatment is tried first. Your doctor may recommend any of the following. Padding and taping the toe area, shoe inserts, changes to footwear, for example wearing shoes with wider toe boxes or flat heels, Anti-inflammatory medicines taken by mouth or injected into the toe area, nerve blocking medicines injected into the toe area, other painkillers, physical therapy. Anti-inflammatories and painkillers are not recommended for long-term treatment. In some cases, surgery is needed to remove the thickened tissue and inflammed nerve. This helps relieve pain and improve foot function. Numbness after surgery is permanent.intermetatarsal neuroma

Surgical Treatment

Surgery is occasionally required when the conservative treatment is not able to relieve your symptoms, particularly if you have had pain for more than 6 months. 80% of patients who require surgery report good results, with 71% of people becoming pain-free.

Prevention

The best way to prevent a neuroma is by avoiding the things that cause them. Review your risk factors. If relatives have had similar problems, or if you know that you pronate or have any problem with the mechanics of your foot, talk with a podiatric physician about the correct types of shoes and/or orthoses for you. If you are not sure whether you have such a problem, the podiatric professional can analyze your foot, your stride and the wear pattern of your shoes, and give you an honest evaluation. Remember, though, that sometimes neuromas, like other conditions, can develop for no discernible reason. With this in mind, be good to your feet, and be aware of any changes or problems. Don?t wait to report them.
