Chronic Foot Pain Causes

Mortons Neuroma Prevention

Overview

MortonMorton's neuroma is a swollen or thickened nerve in the ball of your foot. When your toes are squeezed together too often and for too long, the nerve that runs between your toes can swell and get thicker. This swelling can make it painful when you walk on that foot. High-heeled, tight, or narrow shoes can make pain worse. Sometimes, changing to shoes that give your toes more room can help.

Causes

Anything that causes compression or irritation of the nerve can lead to the development of a neuroma. One of the most common offenders is wearing shoes that have a tapered toe box, or high-heeled shoes that cause the toes to be forced into the toe box. People with certain foot deformities - bunions, hammertoes, flatfeet, or more flexible feet - are at higher risk for developing a neuroma. Other potential causes are activities that involve repetitive irritation to the ball of the foot, such as running or court sports. An injury or other type of trauma to the area may also lead to a neuroma.

Symptoms

Symptoms of interdigital neuroma typically manifest as a sharp, burning or tingling sensation in the forefoot. The pain radiates toward the lesser toes and is aggravated by shoe wear. The pain is relieved when the shoe is removed and the forefoot is massaged. Sometimes the symptoms involve specific toes.

Diagnosis

The exact cause of Mortons neuroma can often vary between patients. An accurate diagnosis must be carefully made by the podiatrist through thorough history taking and direct questioning to ensure all possible causes are addressed. The podiatrist will also gather further information about the cause through a hands on assessment where they will try to reproduce your symptoms. A biomechanical and gait analysis will also be performed to assess whether poor foot alignment and function has contributed to your neuroma.

Non Surgical Treatment

Treaments may include wearing wider shoes to reduce the squeezing force on the foot. Adding a specially made padding to shoes to offload the pressure on the ball of the foot (called a metatarsal dome) Addressing the foot and lower limb biomechanics. This involves looking at foot stability and if needed prescribing an orthotic device to correct your foot position. Anesthetic & Cortisone injections. This is done when the above treatments are insufficient. The trauma is sometimes so great that conservative treatment cannot control the inflammation or cause of the pain. A series of injections are performed to control the inflammation or to temporarily settle the nerve. An ultrasound and cortisone injection can be prescribed by your podiatrist.interdigital neuroma

Surgical Treatment

If conservative treatments haven't helped, your doctor might suggest injections. Some people are helped by the injection of steroids into the painful area. In some cases, surgeons can relieve the pressure on the nerve by cutting nearby structures, such as the ligament that binds together some of the bones in the front of the foot. Surgical removal of the growth may be necessary if other treatments fail to provide pain relief. Although surgery is usually successful, the procedure can result in permanent numbness in the affected toes.

Prevention

Although the exact causes of neuromas are not completely known, the following preventive steps may help. Make sure your exercise shoes have enough room in the front part of the shoe and that your toes are not excessively compressed. Wear shoes with adequate padding in the ball of the foot. Avoid prolonged time in shoes with a narrow toe box or excessive heel height (greater than two inches).
