Morton's neuroma is a swollen or thickened nerve in the ball of your foot. When your toes are squeezed together too often and for too long, the nerve that runs between your toes can swell and get thicker. This swelling can make it painful when you walk on that foot. High-heeled, tight, or narrow shoes can make pain worse. Sometimes, changing to shoes that give your toes more room can help.
There are orthoses and corrective shoes that can effectively alleviate disturbances to foot mechanics. A podiatric physician can prescribe the best corrective footwear and shoe inserts for all activities, work, exercise, play, walking, shopping and more, based on an analysis of the patient?s foot and his or her lifestyle. Improper footwear. Podiatric physicians have long believed that constricting, narrow, poor-fitting shoes with a tight or pointed toe box tend to compress the end of the foot, leading to abnormal motion of the foot and to excessive pressure in the area of the nerve. High-heeled shoes are a particular culprit here, since they put pressure on the area around wearer?s toes and the ball of the foot.
The most common symptom of Morton's neuroma is localized pain in the interspace between the third and fourth toes. It can be sharp or dull, and is worsened by wearing shoes and by walking. Pain usually is less severe when the foot is not bearing weight.
The clinical symptoms should quickly lead your doctor to suspect a neuroma. When examined, the doctor may feel a "click" which is known as Mulder's sign. There may be tenderness in the interspace. The metatarsal bones will also be examined both clinically (and often with an xray). Tenderness at one of the metatarsal bones can suggest an overstress reaction (pre-stress fracture or stress fracture) in the bone. An ultrasound scan can confirm the diagnosis and is a less expensive and at this time, at least as sensitive a test as an MRI. An x-ray does not show neuromas, but can be useful to "rule out" other causes of the pain.
Non Surgical Treatment
Wear shoes with plenty of room for the toes to move, low heels, and laces or buckles that allow for width adjustment. Wear shoes with thick, shock-absorbent soles, as well as proper insoles that are designed to keep excessive pressure off of the foot. High-heeled shoes over two inches tall should be avoided whenever possible because they place undue strain on the forefoot. Resting the foot and massaging the affected area can temporarily alleviate neuroma pain. Use an ice pack to help to dull the pain and improve comfort. Use over-the-counter shoe pads. These pads can relieve pressure around the affected area.
Surgery may be considered in patients who have not responded adequately to non-surgical treatments. Your foot and ankle surgeon will determine the approach that is best for your condition. The length of the recovery period will vary, depending on the procedure performed. Regardless of whether you?ve undergone surgical or nonsurgical treatment, your surgeon will recommend long-term measures to help keep your symptoms from returning. These include appropriate footwear and modification of activities to reduce the repetitive pressure on the foot.
