Restless Legs Syndrome Health Center

Restless Legs Syndrome (RLS) is a neurological disorder that causes pain, unpleasant sensations in the legs and an uncontrollable urge to keep them moving. This pain is the primary symptom of Restless Legs Syndrome and usually worsens at night. Pain and the need to move the legs often occur when a person is trying to go to sleep. This is because the disorder is triggered by lying down and relaxing. When a person with RLS tries to go to bed, the overwhelming need to keep their legs moving can keep them up all night.

Several studies have shown that moderate to severe Restless Legs Syndrome affects up to 10% of the U.S. population. Another 5% are affected by a milder form of RLS. The disorder occurs in both men and women, although it is much more common in women. Restless Legs Syndrome  affects all ages but as someone gets older, the symptoms become longer and much more frequent.
