Morton's neuroma is a condition that affects one of the nerves between the toes. It's also known as Morton's metatarsalgia or interdigital neuroma. In Morton's neuroma, fibrous tissue develops around the nerve, which becomes irritated and compressed. This causes severe pain on the ball of the foot and at the base of the toes. Morton's neuroma can occur on one foot or both feet. It usually affects the nerve between the third and fourth toes, but sometimes the second and third toes are affected.
Morton's neuroma is an inflammation caused by a buildup of fibrous tissue on the outer coating of nerves. This fibrous buildup is a reaction to the irritation resulting from nearby bones and ligaments rubbing against the nerves. Irritation can be caused by Wearing shoes that are too tight. Wearing shoes that place the foot in an awkward position, such as high heels. A foot that is mechanically unstable. Repetitive trauma to the foot such as from sports activities like tennis, basketball, and running. Trauma to the foot caused by an injury such as a sprain or fracture. It is unusual for more than one Morton's neuroma to occur on one foot at the same time. It is rare for Morton's neuroma to occur on both feet at the same time.
Patients will often experience a clicking feeling in the forefoot followed by a sharp shooting pain or a sensation of numbness or pins and needles extending into ends of their toes. Tight narrow fitting shoes may often exacerbate these feelings which become worse after long periods of standing or walking. Once the Mortons nueroma progresses symptoms will become more frequent and often more intense.
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
Treatment for Morton?s Neuroma usually begins conservatively, with a change in lifestyle choices. People suffering from the condition may find pain relief by reducing activity levels, changing footwear, using orthopedic supports, reducing weight. Medications are also available to help relieve the pain of Morton?s Neuroma. Over-the-counter medications are sometimes very helpful in reducing pain and inflammation. Your health care provider can also provide you with anesthetic or corticosteroid injections. These help to numb the area affected by the neuroma, and reduce inflammation.
Surgery. This is the last and most permanent course of action. This surgery is used as a last resort as it often comes with a series of side affects including the risk of making the pain worse. This surgery can be performed by Orthopedic surgeons as well as Podiatric surgeons.
