Hi doctors, can you tell me what is restless leg syndrome?

See below: If you have an urge to move your legs due to "creepy, "crawling, " discomfort, or aching feeling especially at night that gets better with movement and worse at rest than it may have restless legs syndrome (rls). Rls can be due to many secondary causes or be a syndrome on its own. It is best to seek advice of a fellowship trained sleep medicine specialist who can help make that diagnosis.
