Restless legs syndrome (RLS) is a recognized neurological disorder that can interfere with resting or falling asleep. For a restless legs syndrome sufferer, a typical night may involve lying down in bed, feeling ready to go to sleep, and just as the body begins to relax, an uncomfortable sensation begins to overwhelm the legs. Attempts to ignore the crawling, tingling, or itching in the legs, hoping it will go away, only make it worse. The severity of the symptoms varies from person to person, but these 10 symptoms, which are considered to be enough to constitute a restless leg syndrome diagnosis, are listed below.

1. Leg discomfort

It all starts with a deep, uncomfortable sensation within the legs. Many describe the sensations as tingling, jitteriness, a “creepy crawly” feeling, itching, or pulling. These sensations generally occur within the limb rather than on the skin. Sometimes the sensations seem to defy description. Affected people usually don’t describe the condition as a muscle cramp or numbness. They do, however, consistently describe the desire to move their legs.
