Restless Leg Syndrome (RLS)

Restless legs syndrome (RLS) is poorly understood, often misdiagnosed, and believed to be a neurological disorder. RLS may be described as uncontrollable urges to move the limbs in order to stop uncomfortable, painful or odd sensations in the body, most commonly in the legs. Moving the affected body part modulates the sensations, providing temporary relief. The sensations and need to move may return immediately after ceasing movement, or at a later time. RLS may start at any age, including early childhood, and is a progressive disease for a certain portion of those afflicted, although the symptoms have disappeared permanently in some sufferers.

The sensations are unusual and unlike other common sensations, and those with RLS have a hard time describing them. People use words such as: uncomfortable, antsy, electrical, creeping, painful, itching, pins and needles, pulling, creepy-crawly, ants inside the legs, and many others. The sensation and the urge can occur in any body part; the most cited location is legs, followed by arms. Some people have little or no sensation, yet still have a strong urge to move.

Movement will usually bring immediate relief, however, often only temporary and partial. Walking is most common; however, doing stretches, yoga, biking, or other physical activity may relieve the symptoms. Constant and fast up-and-down movement of the leg, coined "sewing machine legs" by at least one RLS sufferer, is often done to keep the sensations at bay without having to walk. Sometimes a specific type of movement will help a person more than another.
