RLS symptoms, which include creepy-crawly, tingling, pulling or burning sensations in the legs, become worse when you're resting. RLS is different from simply wanting to shake your leg a lot while sitting. A strong, sometimes irresistible, urge to move your legs. The need to move is often accompanied by uncomfortable sensations that have been described as creeping, itching, pulling, creepy-crawly, tugging or gnawing.
