Clinical Information
  • A condition in which a person has a strong urge to move his or her legs in order to stop uncomfortable sensations. These include burning, itching, creeping, tugging, crawling, or pain. These feelings usually happen when a person is lying or sitting down, and are worse at night. They can also occur in other parts of the body
  • A condition that occurs while resting or lying in bed; it is characterized by an irresistible urgency to move the legs to obtain relief from a strange and uncomfortable sensation in the legs
  • A disorder characterized by aching or burning sensations in the lower and rarely the upper extremities that occur prior to sleep or may awaken the patient from sleep. Complying with an irresistible urge to move the affected limbs brings temporary relief. Sleep may become disrupted, resulting in excessive daytime hypersomnolence. This condition may be associated with uremia; diabetes mellitus; and rheumatoid arthritis. Restless legs syndrome differs from nocturnal myoclonus syndrome in that in the latter condition the individual does not report adverse sensory stimuli and it is primarily a sleep-associated movement disorder.

  • Restless legs syndrome (rls) causes a powerful urge to move your legs. Your legs become uncomfortable when you are lying down or sitting. Some people describe it as a creeping, crawling, tingling or burning sensation. Moving makes your legs feel better, but not for long. In most cases, there is no known cause for rls. In other cases, rls is caused by a disease or condition, such as anemia or pregnancy. Some medicines can also cause temporary rls. Caffeine, tobacco and alcohol may make symptoms worse.lifestyle changes, such as regular sleep habits, relaxation techniques and moderate exercise during the day can help. If those don't work, medicines may reduce the symptoms of rls
