A neuroma is the swelling of nerve that is a result of a compression or trauma. When the neuroma is present in the space between the third and fourth toes, it is called a Morton’s Neuroma. This is the most common area for a neuroma to form. Neuromas can occur in one or both of these areas and in one or both feet at the same time.
Problems often develop in this area because part of the lateral plantar nerve combines with part of the medial plantar nerve here. When the two nerves combine, they are typically larger in diameter than those going to the other toes. Also, the nerve lies in subcutaneous tissue, just above the fat pad of the foot, close to an artery and vein.
Symptoms
Burning pain, tingling, and numbness in one or two of the toes are common symptoms. Sometimes this pain can become so severe; it can bring tears to a patient’s eyes. It can be sharp or dull, and is worsened by wearing shoes and by walking. Removing the shoe and rubbing the ball of the foot helps to ease the pain. As the nerve swells, it can be felt as a popping sensation when walking. Pain is intermittent and is aggravated by anything that results in further pinching of the nerve.
Treatment
Treatment for the neuroma consists of cortisone injections, orthotics, chemical destruction of the nerve, or surgery. Cortisone may provide relief for many months, but is often not a cure for the condition. To address the abnormal movement of the metatarsal bones, a functional foot orthotic can be used. These devices are custom-made inserts for the shoes that correct abnormal function of the foot.
