Restless legs syndrome is a neurological condition that causes unpleasant sensations in the legs and sometimes arms. People with restless legs syndrome (RLS) feel a strong urge to move their legs in an effort to get more comfortable. But the periods of relief are short-lived. Uncomfortable feelings quickly return. The sensations are often described as creeping, crawling, tugging, gnawing, aching, burning, pulling, tingling or cramping. Any way you describe it, RLS can make sitting or lying down very uncomfortable. People with severe RLS event have difficulty sleeping.
