Restless legs syndrome (RLS) is a neurological disorder characterized by the irresistible urge to move one's body to stop uncomfortable or odd sensations at rest or at bedtime. This disorder commonly affects the legs, but can affect the arms, torso, head, and even phantom limbs. Moving the body part eases the sensations, providing temporary relief. RLS sensations range from pain or an aching in the muscles, to an itch you can't scratch, an unpleasant tickle that won't stop, or even a crawling feeling. These sensations typically begin when relaxing, reading, studying, or trying to sleep.

Most people with RLS suffer from periodic limb movement disorder -- limbs jerk during sleep -- which is a physiologic marker of the disorder and is associated with sleep disruption.

Restless Legs Syndrome is often treated with prescription drugs. It can be caused by low iron levels. Let the medical sleep specialists at Sleep Disorders Center find the right treatment for you.
