Overview
A neuroma develops when a nerve is compressed, injured or pinched, causing swelling and pain. A neuroma in the area between the third and fourth toes, or between the second and third toes, is known as a Morton?s neuroma. Morton?s neuroma causes sharp, burning pain and numbness in the toes and foot. You may feel like you?ve stepped on a tiny hot coal and can?t get rid of it. At the same time, you?ll have the disconcerting experience of not being able to feel your toes. Sometimes the nerve tissue becomes so thickened you can feel or see a lump.
Causes
Occupational hazards. Individuals whose jobs place undue stress on their forefeet (with or without wearing improper footwear) are among those who complain of neuromas. Podiatric physicians report that individuals who work on ladders, or who perform activities on their knees (such as doing landscaping, carpeting, flooring, or other work on the ground) are at risk for this problem, too, since these activities cause stress to the nerve near the ball of the foot. Those who engage in high-impact activities that bring repetitive trauma to the foot (running, aerobics, etc.) have a better than average chance of developing a neuroma at the site of a previous injury. To put it more simply, if you have sustained a previous injury to your foot (a sprain, stress fracture, etc.), that area of your foot will be more prone to neuroma development than an area that has not been injured. However, sports injuries aren?t automatically a ticket to neuromas. Trauma caused by other forms of injury to the foot (dropping heavy objects, for example) can also cause a neuroma to develop at the site of the previous injury. Much though we hate to say it, sometimes neuromas just develop and nobody knows why. The patient doesn?t have a previous injury, is wearing properly fitted shoes, and doesn?t stress his/her feet with any specific activity but the neuroma develops anyway. It is important to remember that some of the factors listed above can work alone, or in combination with each other, to contribute to the formation of neuroma.
Symptoms
Normally, there are no outward signs, such as a lump, because this is not really a tumor. Burning pain in the ball of the foot that may radiate into the toes. The pain generally intensifies with activity or wearing shoes. Night pain is rare. There may also be numbness in the toes, or an unpleasant feeling in the toes. Runners may feel pain as they push off from the starting block. High-heeled shoes, which put the foot in a similar position to the push-off, can also aggravate the condition. Tight, narrow shoes also aggravate this condition by compressing the toe bones and pinching the nerve.
Diagnosis
Morton's neuroma is usually diagnosed by your doctor listening to your symptoms and examining your foot. Sometimes your doctor can feel the 'neuroma', or an area of thickening in your foot, which may be tender. Sometimes, your doctor may suggest an ultrasound scan or MRI scan to confirm the diagnosis but this is not always necessary. Some doctors inject a local anaesthetic into the area where you are experiencing pain. If this causes temporary relief of pain, burning and tingling, it can sometimes help to confirm the diagnosis and show the doctor where the problem is.
Non Surgical Treatment
To help relieve the pain associated with Morton's neuroma and allow the nerve to heal, consider the following self-care tips. Take anti-inflammatory medications. Over-the-counter nonsteroidal anti-inflammatory medications, such as ibuprofen (Advil, Motrin IB, others) and naproxen (Aleve), can reduce swelling and relieve pain. Try ice massage. Regular ice massage may help reduce pain. Freeze a water-filled paper cup or plastic foam cup and roll the ice over the painful site. Change your footwear. Avoid high heels or tight shoes. Choose shoes with a broad toe box and extra depth. Take a break. For a few weeks, reduce activities such as jogging, aerobic exercise or dancing that subject your feet to high impact.
Surgical Treatment
If your pain continues despite several months of conservative treatment, your doctor may recommend surgery to remove the neuroma or to widen the space through which the affected nerve travels. These types of surgery often are done under local anesthesia. If your doctor removes a portion of the affected nerve along with the neuroma, you may develop permanent numbness between the toes.
