Overview

RLS is a condition that makes people constantly want to move their legs, usually in response to an uncomfortable feeling. When you’re sitting or lying down, it typically occurs in the evening or at night. Moving temporarily reduces the unpleasant sensation.

Symptoms

The main symptom of restless legs syndrome is an overwhelming urge to move your legs.

It can also cause an unpleasant crawling or creeping sensation in the feet, calves and thighs.

The sensation is often worse in the evening or at night. Occasionally, the arms are affected, too.

Restless legs syndrome is also associated with involuntary jerking of the legs and arms, known as periodic limb movements (PLM).

Some people have the symptoms of restless legs syndrome occasionally, while others have them every day.

The symptoms can vary from mild to severe. In severe cases, restless legs syndrome can be very distressing and disrupt a person’s daily activities.
