Overview
Restless legs syndrome (RLS) is a neurological disorder that creates an overwhelming urge to move your legs. The condition is also called Willis-Ekbom disease. Most people with RLS experience uncomfortable sensations deep inside their legs, especially when sitting or lying down.
RLS affects about 7-10% of adults in the United States. Women are twice as likely to develop the condition as men. While RLS can occur at any age, symptoms often worsen with age and become more frequent.
The condition can seriously impact your quality of life. Many people with RLS struggle with sleep problems and chronic fatigue, which can affect work performance, relationships, and overall well-being. Getting proper treatment can help you manage symptoms and improve your sleep.
RLS is not contagious and is not caused by laziness or lack of willpower. It's a real medical condition with physical causes in the brain. Many people don't realize they have RLS because they think their symptoms are normal or just part of getting older.
Symptoms & Signs
RLS symptoms typically occur when you're at rest, especially in the evening or at night. The sensations usually affect both legs but can sometimes occur in just one leg or even in your arms.
Symptoms can start suddenly or develop slowly over time. Some people have mild symptoms that only happen occasionally, while others have severe symptoms every night. The uncomfortable feelings can make it very hard to fall asleep or stay asleep.
Primary Symptoms
Uncomfortable leg sensations - feelings described as crawling, creeping, pulling, throbbing, or electric-like sensations deep inside your legs
Uncontrollable urge to move - an overwhelming need to move your legs to relieve the uncomfortable feelings
Symptoms worsen at rest - sensations become more intense when sitting or lying down, especially in the evening
Movement provides relief - walking, stretching, or moving your legs temporarily reduces the uncomfortable sensations
When to Seek Care
Contact a healthcare provider if leg discomfort interferes with your sleep or daily activities. Seek medical attention if you experience symptoms several times per week or if moving your legs no longer provides relief.
Don't wait until symptoms become severe before talking to a doctor. Early treatment can help manage symptoms and reduce their impact on sleep. Your doctor can help you find the right treatment plan for your specific situation.
When to Seek Immediate Care
RLS itself is not usually an emergency. Seek urgent medical care for new severe leg pain or swelling, especially if one leg is affected, because these symptoms may have causes other than RLS that need prompt evaluation.
Causes & Risk Factors
The exact cause of RLS isn't fully understood, but researchers believe it involves problems with dopamine, a brain chemical that controls muscle movement. There are two main types: primary RLS (no known cause) and secondary RLS (caused by another condition).
Scientists think genetics play a big role in RLS. If your parents or siblings have RLS, you're more likely to get it too. Brain imaging studies show that people with RLS have differences in how their brains handle dopamine.
Age
Symptoms typically worsen with age, though RLS can occur at any age
Genetics
Family history increases risk - up to 60% of cases have a genetic component
Lifestyle
Caffeine, alcohol, inactivity, vigorous exercise, and poor sleep can worsen symptoms for some people.
Other Conditions
Iron deficiency, kidney disease, diabetes, and peripheral neuropathy increase risk

Diagnosis
Medical History & Physical Examination
Your doctor will ask detailed questions about your symptoms, including when they occur, how they feel, and what makes them better or worse. They'll also review your medical history, medications, and family history of RLS. A physical exam helps rule out other conditions that might cause similar symptoms.
The diagnosis is primarily based on your description of symptoms. Your doctor will assess whether your symptoms fit the main RLS features, including an urge to move that begins or worsens at rest, improves with movement, and is worse in the evening or at night. They will also consider other conditions that can cause similar symptoms.
Keep track of when your symptoms happen before seeing your doctor. Write down what you're doing when symptoms start and what helps them feel better. This information helps your doctor understand your condition better and plan the right treatment.
Diagnostic Testing
Blood tests - check iron levels, kidney function, and vitamin B12 levels to identify potential underlying causes
Sleep study - measures leg movements during sleep and can detect periodic limb movement disorder
Nerve conduction studies - rule out peripheral neuropathy or other nerve problems that might cause leg discomfort

Treatment Options
Treatment for RLS focuses on relieving symptoms and improving sleep quality. The best approach often combines lifestyle changes with medical treatments, depending on symptom severity.
Finding the right treatment may take time and patience. What works well for one person might not work for another. Your doctor might need to try different medications or dosages to find what works best for you.
Conservative Treatments
Iron treatment may help some people with low iron stores, even without anemia. Have iron studies reviewed by a healthcare professional before taking iron or receiving intravenous iron.
Lifestyle modifications - regular exercise, good sleep hygiene, and avoiding caffeine and alcohol
Leg massages and warm baths - can provide temporary relief from uncomfortable sensations before bedtime
Advanced Treatments
Dopamine agonists such as pramipexole or ropinirole can help some people, but clinicians may avoid long-term use because symptoms can become earlier, more frequent, or more severe over time. Other medicines, including alpha-2-delta ligands, are often considered first.
Alpha-2-delta ligands - gabapentin and similar medications can be effective, especially if you also have pain or anxiety
Opioids - reserved for severe cases that don't respond to other treatments due to addiction potential
Treatment plans should be adjusted as your symptoms change. Your doctor will monitor how well your treatment is working and make changes as needed. Regular check-ins help ensure you're getting the best relief possible.
Living with the Condition
Daily Management Strategies
Establish a consistent bedtime routine that includes relaxing activities like gentle stretching or reading. Keep a symptom diary to identify triggers and patterns. Create a comfortable sleep environment with cool temperatures and minimal distractions. Consider meditation or relaxation techniques to help manage stress, which can worsen symptoms.
Small changes in your daily routine can make a big difference in managing RLS. Pay attention to what makes your symptoms worse and try to avoid those triggers. Being patient with yourself as you adjust to living with RLS is important.
Exercise & Movement
Regular moderate exercise can reduce RLS symptoms, but avoid intense workouts close to bedtime. Walking, swimming, and yoga are excellent choices. Gentle leg stretches before bed can help prepare your muscles for rest. Avoid prolonged periods of sitting - take breaks to move around during long car rides or desk work.
The best time to exercise is in the morning or early afternoon. Regular moderate exercise may help some people manage RLS symptoms and sleep better. Even 30 minutes of activity most days of the week can help reduce RLS symptoms.
Prevention
Maintain healthy iron levels - eat iron-rich foods like lean meat, spinach, and beans, and have your iron levels checked regularly
Practice good sleep hygiene - go to bed and wake up at the same time daily, avoid screens before bedtime
Limit caffeine and alcohol - especially in the afternoon and evening when RLS symptoms typically worsen
Stay physically active - engage in regular moderate exercise, but avoid vigorous activity close to bedtime
Manage underlying conditions - work with your doctor to control diabetes, kidney disease, or other health issues that may contribute to RLS
Review medications - discuss with your healthcare provider if any of your current medications might be worsening symptoms
Prevention strategies work best when you stick with them consistently. Building healthy habits takes time, but the improvements to your sleep and quality of life are worth the effort. Your doctor can help you create a prevention plan that fits your lifestyle.
Frequently Asked Questions
If you notice new or changing RLS symptoms after starting any medication, discuss this with your healthcare professional.
