What Is Mortons Neuroma
Overview Morton?s neuroma is a swollen nerve in the distal portion of the foot. The enlarged portion of the nerve represents scarring within the plantar nerve that occurs after chronic compression and/or repetitive injury. This may come about when the toes are squeezed together for too long, as can occur with the chronic use of high heels. The nerve that runs between your toes will swell and thicken. This can cause pain when walking. The symptoms of Morton?s neuroma can include burning pain in the foot, the feeling of a lump inside your foot, pain between the third and fourth toes typically but it can occur between other toes. Causes It's not always clear what causes Morton's neuroma, but several things seem to aggravate it. These include other foot-related problems and wearing restrictive footwear. It's thought that Morton's neuroma may be caused by the toe bones (metatarsal bones) pressing against the nerve when the gap between the bones is narrow. This causes the nerve and surrounding tissue to thicken. Symptoms Symptoms include: pain on weight bearing, frequently after only a short time. The nature of the pain varies widely among individuals. Some people experience shooting pain affecting the contiguous halves of two toes. Others describe a feeling like having a pebble in their shoe or walking on razor blades. Burning, numbness, and paresthesia may also be experienced. Morton's neuroma lesions have been found using MRI in patients without symptoms. Diagnosis Metatarsal bones will be examined clinically, and often an x-ray will be taken to assess the particular case and ensure against other conditions, including fracture. When the foot is examined by a doctor, he may feel a characteristic ?click,? referred to as Mulder?s sign, and the interspaces between toe bones will often be tender. The doctor may put pressure on these areas to localize the site of pain and test for other conditions, including calluses or stress fractures. Range of motion tests will also be applied to rule out arthritis or joint inflammations. X-rays may be required to ensure there are no stress fractures or arthritis within the joints that join the toes to the foot. Tenderness in one or more metatarsal bones may imply a pre-stress fracture or stress-fracture. An ultrasound scan may be used to confirm diagnosis of Morton?s Neuroma, as x-ray will not detect the condition, (but can confirm that the bones are uninjured). 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. Surgical Treatment If symptoms Do compression socks help with Achilles tendonitis? not respond to any of the above measures then surgery may be suggested. This involves a short 30 minute operation to either remove tissue to take pressure off the nerve or to remove the nerve causing the pain. The surgery can be done as a day case but it will be two or three weeks before you can be fully active on your feet. There may be some lingering numbness afterwards if the nerve is removed. But surgery is successful in around 80% of cases. There is a small risk of complications such as infection and thickening of the skin on the soles of the feet.
