Symptoms include an urge to move the legs often associated with uncomfortable feeling in the legs (e.g. tingling, creepy, itching, pulling or aching) during periods of inactivity, including both sleep and wakefulness. Symptoms may also include involuntary jerking of the limbs that intensifies in the evening or at night and is relieved by movement.

Restless Legs Syndrome (RLS) is a neurologic sensorimotor disorder that is characterized by an overwhelming urge to move the legs when they are at rest. The urge to move the legs is usually, but not always, accompanied by unpleasant sensations. It is less common but possible to have RLS symptoms in the arms, face, torso, and genital region. RLS symptoms occur during inactivity and they are temporarily relieved by movement or pressure. Symptoms of RLS are most severe in the evening and nighttime hours and can profoundly disrupt a patient's sleep and daily life.

If possible, bring a diary of your sleep as well as a record of the occurrence and severity of your symptoms with you.

You can expect that he or she will ask what time your symptoms occur, when they are most severe, what you were doing before the onset of symptoms, and how much time elapses before you are able to get to sleep due to your RLS. Your doctor will also need a record of your sleep quality and quantity during the time when symptoms appear and whether or not you experienced any pain along with the RLS symptoms. Until recently, there were no FDA-approved drugs for the treatment of RLS. In May 2005, a drug called Requip® (ropinirole hydrochloride) that is commonly used to treat Parkinson disease was giv...
