Restless Legs Syndrome – What It Is
Restless legs syndrome (RLS) is marked by sensations in the legs that range from mildly uncomfortable to extremely irritating and painful and are accompanied by an almost irresistible urge to move them to get some relief. Because these uncomfortable sensations generally start or become worse at rest, at night, and while lying down, they often lead to chronic sleep problems, stress, and discomfort.
Research suggests that RLS may be a common and largely undertreated condition that affects slightly more women than men. Although anyone can develop RLS, about half the people with the condition say other family members have it, too. RLS can occur as a consequence of certain medical conditions, and new research shows it can increase the risk of heart disease.
Pregnancy, certain medical conditions, and several drugs, including cold and allergy medications and antinausea drugs, may increase a person's likelihood of suffering from RLS.
Stress, anxiety, and other psychological problems may make symptoms worse, but RLS is not a psychological condition.
RLS shouldn't be confused with periodic limb movement disorder (PLMD), a condition that causes leg muscles to involuntarily and intermittently jerk or twitch every 10 to 60 seconds, sometimes throughout the night. Although 80% of those with RLS also have PLMD, most people with PLMD do not have RLS.
