Overview
This is a painful condition affecting a small nerve in the foot. It occurs when the five long bones that run the length of the foot get pushed together, pinching the nerve in between. This friction on the nerve causes it to thicken and inflame causing pain. The condition gets its name from an American surgeon, George Morton.
Causes
The pain of Morton's neuroma occurs when the nerve connecting the toe bones (metatarsal bones) becomes irritated or compressed. The exact cause of the irritation is unknown, but it may be the metatarsal bones pressing against the nerve when the gap between the bones is narrow. This causes the nerve and surrounding tissue to thicken. Some experts believe that a number of other foot problems, including flat feet, high foot arches, bunions and hammer toes, may also play a role in Morton's neuroma.
Symptoms
The primary symptoms include sharp, shooting pain, numbness or paresthesia in the forefoot and extending distally into the toes, typically in the region of the third and fourth toes. Symptoms are aggravated with narrow toe box shoes or those with high heels. There is usually a reduction of symptoms when walking barefoot or wearing shoes with an appropriately wide toe box. Symptoms are also aggravated with shoes that are tied too tight.
Diagnosis
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
Common treatments involve wearing different shoes or using arch supports. Resting the foot, massaging the toes and using an ice pack may work for some people. A GP or a podiatrist (foot specialist) may also recommend anti-inflammatory painkillers or a course of steroid injections. Numbing injections, in which alcohol and a local anaesthetic are injected into the affected area of the foot, may also be effective. In extreme cases, when the condition does not respond to treatment, day case surgery may be needed.
Surgical Treatment
When conservative measures are unsuccessful, surgery can be a good choice in the treatment of Morton's neuroma. The operation for Morton's neuroma does not require an overnight hospital stay. The anesthetic used is an ankle block, which completely numbs the foot during the surgery. The physician removes the neuroma from an incision made on the top of the foot between the involved metatarsal heads. The nerve to the interspace is exposed and cut next to the metatarsal heads.
Prevention
Always warm-up thoroughly before vigorous athletics. Avoid activities that cause pain. Stretch and strengthen the feet through gradual exercise.
