Restless Leg Syndrome Restless Leg Syndrome (RLS) is a disorder that was described in medical texts over 2,000 years ago. Currently the disorder is defined by the combination of three symptoms.   •  Painful or unusual feelings in the legs.   • The feeling is accompanied by an irresistable urge to move the legs.   • The feeling is temporarily relieved by moving the legs. RLS is a relatively common condition effecting about 5% of adults. It often runs in families and is believed to be a genetic condition. It can develop at any age, but most often starts in the teenage years. While most cases of RLS are of unknown cause, sometimes RLS occurs in the presence of specific conditions. RLS can develop during pregnancy and the symptoms go away once the baby is delivered. Patients on kidney dialysis frequntly experience RLS. In some people there is evidence of low (or low-normal) iron levels, and therefore iron supplementation may provide benefit. The good news for all sufferers of RLS is that there are very effective treatments. Typically a prescribed medication taken before bedtime will relieve or eliminate the symptoms.
