The regular moving, spreading and throwing around the legs during sleep is called the Restless legs syndrome (RLS) – a disorder that causes the strong, often strange and unpleasant, feeling of needing to move your legs. RLS can make the urge to move your legs feel overwhelming. People with RLS have described the feeling as: Aching; Burning; Crawling; Creeping; Electric shocks; Itching; Pulling and Tingling. The unpleasant feeling will only go away for people once they move their legs around, which is a problem because it happens when people are resting and inactive. RLS can make it difficult for people to fall asleep, which can lead to depression, mood swings and other health problems. The disorder is twice as common in women as it is in men, and it can begin at any age.
