Restless legs
Disorder has many causes.
By Dr. Tedd Mitchell
For most people, an opportunity to sit or lie down means a chance to unwind. But for those who suffer from restless legs syndrome, sitting or lying down can be anything but relaxing. The condition, which is estimated to affect up to 10% of the population, makes getting rest a difficult task.
RLS is a neurological disorder that medical science still doesn't know a great deal about. If you have the symptoms, see your doctor to determine if they are being caused by something correctable. RLS, which can have a major effect on sleep, has been associated with pregnancy, iron deficiency, anemia, chronic kidney disease and dialysis, pain and numbness in the hands and feet and even attention deficit disorder. Additionally, RLS tends to run in families, so a history of this in a parent could raise your risk of having it.
If you suspect you may have RLS, talk with your doctor. There are no lab tests to identify RLS, so the diagnosis is based upon your medical history and an examination. Treatment options include lifestyle changes and medications.

Diagnosing RLS
Four things establish that someone has restless legs syndrome:
Symptoms such as a strong urge to move the legs, often accompanied by uncomfortable sensations.
Symptoms that begin when legs are resting.
Symptoms that abate once legs are moving.
Symptoms that worsen at night (especially when lying down).
