Morton’s neuroma is a common foot problem. It is defined as any irritative process of a nerve near ball of the foot. This most commonly affects the 3rd and 4th toes. Symptoms of this condition are typically pain, burning, tingling, numbness, and cramping. People often feel as if they were walking with a rock in their shoe. The pain is usually worsened by walking and relieved by rest and massage.

Repetitive trauma and pressure causes the nerve to become irritated. This can lead to enlargement and thickening of the nerve. Wearing tight or high-heeled shoes can cause a neuroma. Constricting shoes can pinch the nerve between the toes causing severe pain. Occupations requiring repetitive motions of the foot can also cause a neuroma.

Treatment usually starts with shoe modifications. A shoe that has a wide toe box for more room is recommended. An orthotic is often prescribed to unload pressure. Changing activity level may be necessary for a few weeks. If conservative care does not provide relief, surgery may be needed.
