Morton's neuroma is defined as a thickening of nerve tissue between the third and fourth toes. The exact cause is unknown, but researchers believe tight shoes, high heels, high foot arches, flat feet, bunions and hammer toes increase the risk of a Morton's neuroma developing. Morton's neuroma will often cause foot pain between the third and fourth toes, numbness and tingling. After a doctor rules out a fracture, she generally will order an ultrasound, which can detect a Morton's neuroma. A variety of treatments are available.
Rest
A doctor will often recommend conservative treatments for Morton's neuroma, such as rest. Using crutches for a few days may help the inflammation around the neuroma to settle down. Doctors often recommend avoiding exercise that involves walking, running or jumping until the condition improves. Additionally, better fitting shoes or orthotics can improve symptoms, states MayoClinic.com. If a patient does not have stomach, liver or kidney problems, a doctor might recommend over-the-counter medications to reduce pain and inflammation.
Corticosteroid Injections
A doctor may recommend a corticosteroid injection into the Morton's neuroma, states MayoClinic.com. A neuroma is painful primarily because of inflammation of the nerve. Therefore, injecting an anti-inflammatory medication, such as a corticosteroid, can relieve the symptoms of a Morton's neuroma. A corticosteroid can only be injected three times per year to prevent side effects that include weight gain and high blood pressure.
Alcohol Injections
Diluted alcohol injections are a new and promising treatment for a Morton's neuroma, according to MayoClinic.com. MayoClinic.com further states that two studies have shown promising results with this procedure. Because of this new treatment, a doctor may not yet provide it.
Surgery
Surgery may be necessary if conservative treatments fail. A surgeon will remove the neuroma and the nerve, which may provide relief. However, removing the neuroma may cause numbness in the foot. Therefore, a patient and his doctor should thoroughly discuss the risks and benefits of this surgery.
