What is restless legs syndrome?
Restless legs syndrome (RLS) is a sensorimotor disorder characterized by abnormal or unpleasant sensations occurring in the legs. These unpleasant sensations can lead to an overwhelming urge to move the legs. Restless legs syndrome gets worse during periods of inactivity or when relaxing, especially during the evening. Restless legs syndrome is sometimes mistaken as a sleep disorder when in fact it is a movement disorder that can affect sleep.
