Restless legs syndrome or RLS is considered both a neurological and a sleep disorder. It involves abnormal sensations in the legs that interfere with falling or staying asleep. For a person with restless legs syndrome, just as the body starts to relax before sleep, an uncomfortable sensation begins to overwhelm the legs. Attempts to ignore the crawling, tingling, or itching tends to only make it worse.
It all starts with an unusual, uncomfortable sensation in the legs. Many people describe this as a tingling, jitteriness, itching, creepy crawly feeling, or pulling. These sensations generally occur within the limb rather than on the skin, but the feelings are not usually described as muscle cramps or numbness. Regardless of the description, the result is an overwhelming urge to move the legs.
