Dealing With Mortons Neuroma
Overview
Morton's neuroma, also called Morton's metatarsalgia, Morton's disease, Morton's neuralgia, Morton metatarsalgia, Morton nerve entrapment, plantar neuroma, or intermetatarsal neuroma is a benign (non-cancerous) growth of nerve tissue (neuroma) that develops in the foot, usually between the third and fourth toes (an intermetatarsal plantar nerve, most commonly of the third and fourth intermetatarsal spaces). It is a common, painful condition.
Causes
A Morton's Neuroma is not a true neuroma, which is a tumor that is generally benign. Rather, it is an enlargement of the nerve where it goes between the metatarsal bones of the foot. Because the nerve no longer fits between the gap, the pressure causes pain and sometimes numbness. This enlargement of the nerve is often an inflammation due to irritation. If the forefoot becomes compressed due to shoes that are too narrow, the nerve becomes damaged and inflamed. This inflammation means the nerve no longer fits in the space between the bones, creating further irritation and more inflammation. If this vicious circle can be broken, the problem may be resolved. However, in some situations the nerve can have fibrous tissues formed around it, which may require the destruction of the nerve or surgical removal.
Symptoms
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.
Diagnosis
Morton's neuroma is usually diagnosed by your doctor listening to your symptoms and examining your foot. Sometimes your doctor can feel the 'neuroma', or an area of thickening in your foot, which may be tender. Sometimes, your doctor may suggest an ultrasound scan or MRI scan to confirm the diagnosis but this is not always necessary. Some doctors inject a local anaesthetic into the area where you are experiencing pain. If this causes temporary relief of pain, burning and tingling, it can sometimes help to confirm the diagnosis and show the doctor where the problem is.
Non Surgical Treatment
If symptoms are severe or persistent and self-help measures did not help, the doctor may recommend corticosteroid injections, a steroid medication that reduces inflammation and pain is injected into the area of the neuroma. Only a limited number of injections are advised, otherwise the risk of undesirable side effects increases, including hypertension (high blood pressure) and weight gain. Alcohol sclerosing injections, studies have shown that alcohol injections reduce the size of Morton's neuromas as well as alleviating pain. This is a fairly new therapy and may not be available everywhere. The doctor injects alcohol in the area of the neuroma to help sclerose (harden) the nerve and relieve pain. Injections are typically administered every 7 to 10 days. For maximum relief 4 to 7 injections are usually needed.
Surgical Treatment
For those who are suffering severely with Morton?s Neuroma, surgery is a possibility. An orthopedic surgeon can remove the growth and repair your foot relatively easily. However, Morton?s Neuroma surgery is associated with a lengthy recovery time and there is a possibility that the neuroma may return.
