There is no specific diagnostic test for RLS. When you go to your health care professional, he or she may use the following criteria to help determine whether or not you have RLS:
- You have an urge to move your legs usually accompanied by uncomfortable leg sensations. These sensations are different from muscle cramps and numbness, and are often described as burning, creeping, crawling, aching or tugging. Usually starting in the lower legs, symptoms can spread to other parts of the body, such as the feet, chest, and arms. While often described as uncomfortable or irritating, sometimes these sensations can be painful.
- Your symptoms are partially or totally relieved by movement. By moving or stretching, the unpleasant sensations can be partially or totally relieved. The kinds of movements that help are often repetitive, such as pacing, rocking or shaking.

In the early morning, people with RLS often find some relief from the unpleasant sensations. However, as the day continues, symptoms get increasingly worse. Throughout the night, these irritating sensations and feelings often reach their peak.

Your doctor will also need a record of your sleep quality and quantity during the time when symptoms
