Restless legs syndrome — sometimes referred to as Willis-Ekbom disease — is a disorder in which unpleasant tickling or itching sensations create an urge to move one’s legs. It is considered a sleep disorder because it often affects people as they are going to sleep or relaxing. Many people with restless legs syndrome also experience limb jerking during sleep.
Moving the legs usually provides temporary relief, and many people who have restless leg syndrome are compelled to walk to relieve their symptoms. Restless legs syndrome can also be treated with various pharmaceuticals, though you should speak with a sleep medicine specialist before taking medications.
