Restless Legs

Restless legs syndrome (RLS) is a condition characterized by an uncomfortable, powerful urge to move the legs, particularly when resting or attempting to sleep.

Overview

Restless legs syndrome (RLS) causes a powerful urge to move your legs. Your legs become uncomfortable when you are lying down or sitting. Some people describe it as a creeping, crawling, tingling, or burning sensation. Moving makes your legs feel better, but not for long. RLS can make it hard to fall asleep and stay asleep.

Causes and Contributing Factors

In most cases, there is no known cause for RLS. In other cases, RLS is caused by a disease or condition, such as anemia or pregnancy. Some medicines can also cause temporary RLS. Caffeine, tobacco, and alcohol may make symptoms worse.

Management

Lifestyle changes, such as regular sleep habits, relaxation techniques, and moderate exercise during the day can help. If those don't work, medicines may reduce the symptoms of RLS.

Related Conditions

Most people with RLS also have a condition called periodic limb movement disorder (PLMD). PLMD is a condition in which a person's legs twitch or jerk uncontrollably, usually during sleep. PLMD and RLS can also affect the arms.

Frequently Asked Questions

You should see a doctor if your RLS symptoms are frequent, severe, significantly disrupt your sleep, or interfere with your daily activities. A doctor can help determine if there's an underlying cause, like anemia, and discuss appropriate treatment options, including medication if lifestyle changes aren't enough.
While there's no specific RLS diet, some people find relief by ensuring adequate iron intake, especially if anemia is a contributing factor. Discussing iron supplements with a doctor is important, as too much iron can be harmful. Avoiding caffeine and alcohol is also often recommended.
lthough RLS primarily affects the legs, the uncomfortable sensations and urge to move can sometimes occur in other body parts, such as the arms, torso, or even the head. This is less common but can happen, especially in conjunction with periodic limb movement disorder (PLMD).
Effective lifestyle changes include establishing a consistent sleep schedule, avoiding caffeine, alcohol, and tobacco, especially in the evening, and engaging in moderate, regular exercise during the day. Relaxation techniques like warm baths, massage, or stretching before bed can also be beneficial.
