Morton’s neuroma is a condition that affects one of the nerves that run between the long bones (metatarsals) in the foot. The exact cause is not certain. Symptoms include pain, burning, numbness and tingling between two of the toes of the foot. About a quarter of people just need simple treatments including modification of their footwear. Sometimes surgery is needed for long-standing (chronic) symptoms.
Morton’s Neuroma is a foot condition caused from an abnormal function of the foot that leads to bones squeezing a nerve usually between the 3rd and 4th metatarsal heads. Symptoms of Morton’s Neuroma often occur during or after you have been placing significant pressure on the forefoot area, while walking, standing, jumping, or sprinting. This condition can also be caused by footwear selection. Footwear with pointed toes and/or high heels can often lead to a neuroma. Constricting shoes can pinch the nerve between the toes, causing discomfort and extreme pain.
While the condition may at first only appear during heavy repetitive stress or when wearing particular shoes which aggravate the foot, the Neuroma can become increasingly inflamed and produce more constant discomfort, lasting days or weeks. Runners may experience pain pushing off from starting blocks. Tight or narrow shoes as well as high heels likewise aggravate the Neuroma. A checklist of symptoms includes burning pain, occasionally numbness in the ball of the foot. Radiating pain from the ball of the foot to the toes. Intensifying pain during activity and when wearing shoes. Occasional numbness, discomfort, tingling or ?electrical shock sensation? in the toes. Pain between the third and fourth toes, often occurring from the outer side of one toe to the inner side of the adjoining toe. Pain upon leaving the starting blocks in running sports.
You should visit a doctor or podiatrist (foot doctor) if you have pain or tingling that does not stop. Your health care provider will examine your feet and will apply pressure on the spaces between the bones of the toes to determine the location of the foot pain. The doctor may order X-rays to rule out other conditions associated with foot pain, such as a stress fracture or arthritis. X-rays alone will not show whether or not a neuroma is present, so an ultrasound scan or magnetic resonance imaging (MRI) test may be done to confirm the diagnosis. A diagnostic procedure called an electromyography is sometimes used to rule out nerve conditions that may cause symptoms like those of associated with Morton?s neuroma.
Non Surgical Treatment
Conservative treatment for Morton?s neuroma involves footwear that allows your forefoot to spread. High-heeled shoes cause neuromas by squeezing and stretching your involved intermetatarsal nerve across the ball of your foot and should be avoided as often as possible. A shoe that possesses any toe spring will also place more stress on your foot nerves and increase your likelihood of developing a neuroma. Test shoes before you buy them to see if they are appropriate for your feet. Select shoes that have a removable liner or insole, and stand on the liner, noting the position of your foot. If your foot is wider than your liner, that shoe will irritate your neuroma by squeezing your metatarsal bones together.
Surgery to remove the neuroma may be recommended if more conservative treatment does not solve the problem. While surgery usually relieves or completely removes the symptoms, it often leaves a permanent numb feeling at the site of the neuroma.
Wearing shoes that fit properly and that have plenty of room in the toe area may help prevent Morton’s neuroma.
