What is restless legs syndrome (RLS)?

Restless legs syndrome (RLS) is a cause of insomnia (trouble sleeping) for many people. RLS sufferers experience aching, twitching, tingling, burning, or prickling sensations in the lower leg muscles when they lie in bed or sometimes when they are sitting down. The discomfort is relieved only by getting up and standing or walking.

How does it occur?

The exact cause of RLS is not known. It tends to run in families. It is more common after middle age and occurs more frequently in women than in men. Many RLS victims can recall 'growing pains' in their legs during childhood. It may be that a nerve malfunction is involved. RLS has also been linked with alcohol dependence, smoking, too much caffeine (usually from drinking coffee), rheumatoid arthritis, anemia, and diabetes.

What are the symptoms?

Symptoms may include:

• aching, twitching, tingling, burning, prickling in the lower leg when you are lying down or sitting

• relief from the symptoms when you stand up or walk around.

How is it diagnosed?

The diagnosis of RLS is based on your medical history. Your doctor will probably examine you and may order blood tests or other tests to check for an underlying medical problem, such as anemia, rheumatoid arthritis, or diabetes.

How is it treated?

Your doctor can prescribe medication to relieve the symptoms and allow you to sleep. Levodopa (Sinemet), a drug usually used for Parkinson's disease, is often prescribed.

For many people who have RLS, it is a great relief just to learn that there are other RLS sufferers like themselves and that they are not alone.

How can I take care of myself?

• Follow your doctor's advice for relief of your RLS symptoms.

• Avoid or cut back on caffeine (coffee, tea, cocoa, cola).

• Avoid or cut back on alcohol.

• Improve your general health. Eat a healthy diet. Exercise regularly.
