Restless Leg Syndrome (RLS) is a neurological disorder characterized by unpleasant sensations in the legs and an uncontrollable urge to relieve those feelings through stretching and other leg movements. People describe RLS sensations as burning, creeping, tugging, or like insects crawling inside the legs. The most distinctive or unusual aspect of the condition is that lying down and trying to relax activates symptoms. As a result, most people with RLS have difficulty falling asleep and staying asleep. Left untreated, the condition causes exhaustion and daytime fatigue, which adversely affects jobs, personal relationships and daily activities. The first step in treating RLS is to determine whether underlying causes contribute to these unpleasant sensations. With proper treatment, people with RLS can sleep soundly every night and lead normal lives.
