Restless legs syndrome
Restless legs syndrome — Comprehensive overview covers symptoms, treatment of disorder that can cause insomnia.
Definition
Restless legs syndrome (RLS) is a condition in which your legs feel extremely uncomfortable while you're sitting or lying down. It makes you feel like getting up and moving around. When you do so, the unpleasant feeling of restless legs syndrome temporarily goes away.
Restless legs syndrome can begin at any age and generally worsens as you get older. Women are more likely than men to develop this condition. Restless legs syndrome can disrupt sleep — leading to daytime drowsiness — and make traveling difficult.
A number of simple self-care steps and lifestyle changes may help you. Medications also help many people with restless legs syndrome.
Symptoms
Commonly described sensations
People typically describe restless legs syndrome (RLS) symptoms as unpleasant sensations in their calves, thighs, feet or arms, often expressed as:
Crawling
Tingling
Cramping
Creeping
Pulling
Painful
Electric
Tense
Uncomfortable
Itchy
Tugging
Gnawing
Aching
Burning
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 or handle their legs.
It's common for symptoms to fluctuate in severity, and occasionally symptoms disappear for periods of time.
Commonly reported patterns
Common characteristics of RLS signs and symptoms include:
Starts during inactivity. The sensation typically begins after you've been lying down or sitting for an extended period of time, such as in a car, airplane or movie theater.
Relief by movement. The sensation of RLS lessens if you get up and move. People combat the sensation of restless legs in a number of ways — by stretching, jiggling their legs, pacing the floor, exercising or walking. This compelling desire to move is what gives restless legs syndrome its name.
Worsening of symptoms in the evening. Symptoms typically are less bothersome during the day and are felt primarily at night.
Nighttime leg twitching. RLS may be associated with another condition called periodic limb movements of sleep (PLMS). Once called myoclonus, PLMS causes you to involuntarily flex and extend your legs while sleeping — without being aware you're doing it. Hundreds of these twitching or kicking movements may occur throughout the night. If you have severe RLS, these involuntary kicking movements may also occur while you're awake. PLMS is common in older adults, even without RLS, and doesn't always disrupt sleep. More than 4 out of 5 people with RLS also experience PLMD.
