Restless leg syndrome (RLS) is actually a problem with the nervous system that compels an individual to move their legs. This often occurs at rest and interferes with sleep, so it is also considered a sleep disorder. While doctors don't know the exact cause of RLS, they believe it's a genetic disorder and suspect it's aggravated by certain conditions. Chronic disease, such as liver and kidney disease, some prescription drugs, and even pregnancy may increase the severity of the symptoms. While there's no cure for RLS, lifestyle changes, such as more physical activity and abstaining from alcohol, tobacco, and narcotics, may reduce symptoms. Leg massages have also been known to help.Next
