What is restless legs syndrome (RLS)?
Restless legs syndrome (also called RLS) is a condition in which your legs feel very uncomfortable when you are sitting or lying down. It affects both men and women and can occur at any age (including during childhood), but often worsens with age and becomes a problem for older adults. RLS can make sleeping and traveling difficult and uncomfortable. Some cases of RLS are related to other conditions, such as pregnancy, iron-deficiency anemia or kidney failure. Other cases of RLS have no known cause. RLS may be hereditary, which means it can run in your family.
