Restless legs syndrome (RLS) is a disorder that causes a strong urge to move your legs. This urge to move often occurs with strange and unpleasant feelings in your legs. Moving your legs relieves the urge and the unpleasant feelings.

People who have RLS describe the unpleasant feelings as creeping, crawling, pulling, itching, tingling, burning, aching, or electric shocks. Sometimes, these feelings also occur in the arms.

The urge to move and unpleasant feelings happen when you’re resting and inactive. Thus, they tend to be worse in the evening and at night.
