Restless legs syndrome (RLS) are more common during middle and older age. The mechanism is unclear but may involve disturbances in the central nervous system. In RLS, patients complain of a creeping or crawling sensation in the lower extremities when reclining.
To relieve symptoms, patients move the affected extremity by stretching, kicking, or walking. As a result, they have difficulty falling asleep, repeated nocturnal awakenings, or both.
