Restless Legs Syndrome (RLS), also known as Willis-Ekbom disease, is a neurological disorder that causes an uncontrollable urge to move the legs. People with RLS often experience uncomfortable sensations in their legs, such as tingling, itching, or crawling. These sensations typically occur at rest and are most pronounced during the evening or night, leading to difficulties falling asleep. The urge to move the legs is often irresistible, and moving temporarily relieves the discomfort. This condition can significantly impact the quality of sleep and overall well-being.
