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.
