restless legs syndrome [RLS]

Restless legs syndrome (RLS) is a sleep disorder of the brain — a neurologic disorder. It causes an overpowering urge to move your body, especially your legs. This happens along with other sensations described as pulling, creeping, tugging, throbbing, itching, aching, burning, or crawling. Symptoms are usually worse when you’re resting or trying to sleep.
