Restless Legs Syndrome: What You Should Know

Am Fam Physician. 2008 Jul 15;78(2):243.

What is restless legs syndrome?

Restless legs syndrome (RLS) is a condition that makes your legs feel uncomfortable. This feeling may make you want to move your legs. The feeling usually happens in the evening or at night. It may be worse while you are resting. Taking a walk or massaging your legs may help you feel better.

Who gets RLS?

About 10 percent of adults have RLS. It tends to run in families. RLS is more common as people get older, but some people get it before 18 years of age. The cause of RLS is not always clear. Some conditions like anemia and kidney disease may cause RLS. You can also get it when you are pregnant. Some medicines may cause RLS or make it worse.

How can my doctor tell if I have RLS?

Tell your doctor about your symptoms. He or she may ask you these questions:

  • Do you feel like you need to move your legs because of an uncomfortable feeling?

  • Do you feel worse when you are resting?

  • Do you feel better when you are active?

  • Do you feel worse in the evening or at night?

Your doctor may do a blood test to make sure your kidneys are working correctly. He or she may also check your iron level. Low iron can cause RLS.

How is it treated?

Your legs may feel better if you avoid caffeine, cigarettes, and alcohol. Exercise may also help. If you are on medicines that could make RLS worse, your doctor may change them. He or she may give you iron supplements if your iron is low. Medicines that treat Parkinson's disease, seizures, and pain may also treat RLS.
