This condition most commonly occurs in the area of the third and fourth toes but can also affect other toes.
Morton's neuroma develops when the nerve running between the toes is damaged due to prolonged irritation or pressure. The nerve most commonly affected is the plantar interdigital nerve, which runs between the heads of the metatarsal bones. In this area, thickening of the nerve tissue, known as a neuroma, can occur.
The exact cause of Morton's neuroma is not known, but it is believed that a combination of pressure, friction, and traumatic injuries leads to inflammation of the nerve. Certain factors can increase the risk of Morton's neuroma, such as wearing tight shoes, high heels, flat feet, foot deformities, and excessive stress.
Diagnosis
Diagnosis of Morton's neuroma is based on a physical examination and imaging tests such as X-rays, ultrasound, and MRI. During the examination, the doctor can identify the area of the Morton's neuroma through palpation and pressure testing and assess the degree of sensitivity of the affected area.
Treatment
The treatment of Morton's neuroma depends on the severity of the symptoms. For mild symptoms, shoe inserts or wearing more comfortable shoes may help. Nonsteroidal anti-inflammatory drugs (NSAIDs) can reduce pain and inflammation. In more severe cases, a corticosteroid injection into the affected area can alleviate pain and reduce inflammation. If conservative treatment methods are not successful, surgical removal of the neuroma may be necessary.
