(HealthDay News) -- Restless legs syndrome (RLS) is a nervous system disorder that's characterized by an itchy twitching of the legs during rest that's relieved by moving them.

The National Heart, Lung, and Blood Institute says typical symptoms include:

• Feeling a crawling, tingling, burning, aching, pulling or itching sensation in the legs.
• Having the urge to move worsens when you are still.
• Walking and other types of movement alleviate the urge.
• Having symptoms that worsen late in the day.
