Restless legs syndrome (RLS) is marked by uncomfortable leg sensations that occur continually while the body is at rest. It may be a central nervous system disorder and occasionally is associated with iron-deficiency anemia, pregnancy or diabetes. RLS is the basic cause of sleep deprivation for up to an estimated 4 million adult Americans. RLS is characterized by the following signs and symptoms:
- The urge to move the legs, which is often accompanied by uncomfortable sensations in the foot, calf or upper leg (These sensations are usually described as a creeping or crawling feeling and may sometimes be experienced as a tingling, cramping or burning sensation.)
- The need to move the legs to relieve the discomfort by stretching, bending or rubbing the legs, tossing or turning in bed, or getting up and pacing the floor.
- A worsening of discomfort when lying down, especially when trying to fall asleep at night.
- A tendency to experience the most discomfort late in the day and at night.
- Continuous nighttime sleep disruption.
- Daytime fatigue.
