Restless leg syndrome, also known as Willis-Ekbom disease, is a condition that causes a strong urge to move the legs, usually accompanied by an uncomfortable sensation. Symptoms typically begin or worsen while sitting or lying down, are most noticeable in the evening or at night, and are temporarily relieved by movement such as stretching, pacing, or walking.
RLS can begin at any age and tends to become more noticeable over time. It can also be associated with periodic limb movements during sleep, which cause the legs to twitch or kick throughout the night and can further disrupt sleep quality.
