Overview

Restless legs syndrome (RLS) is a condition that causes a very strong urge to move the legs. The need to move usually is caused by aching or an uncomfortable feeling in the legs. It typically happens in the evening or at night when sitting or lying down. Moving eases the feeling for a short time.

Restless legs syndrome can begin at any age and tends to get worse with age. It can make it hard to sleep, which affects daily activities. RLS also is known as Willis-Ekbom disease.

Simple self-care steps and lifestyle changes may help relieve symptoms. Medicines also help many people with RLS.

Causes

Heredity

Sometimes RLS runs in families, especially if the condition starts before age 40. Researchers have found sites on the chromosomes where genes linked to RLS may be present.

Complications

Restless legs syndrome (RLS) symptoms can range from mild to serious. Many people with the condition find it hard to fall asleep or stay asleep, which may affect their quality of life. This can cause depression in some people. Not being able to sleep also may lead to excessive daytime drowsiness. RLS can even interfere with napping.
