Restless legs feeling

Overview

Restless legs syndrome (RLS) is a condition that causes a strong, often uncomfortable urge to move your legs. It usually happens when you are sitting still or lying down, especially in the evening or at night. The feeling is often described as creeping, crawling, tingling, or aching. Moving your legs can give temporary relief, but the sensation often returns when you stop.

Yes, restless legs syndrome is fairly common. It affects about 5 to 10 in every 100 adults. Many people have mild symptoms that do not cause significant problems.

Restless legs syndrome can affect people of any age, including children, but it is more common in middle-aged and older adults. Women are about twice as likely as men to have RLS. People with a family history of RLS have a higher chance of developing it.

Symptoms

Common symptoms

• A strong urge to move your legs, often along with uncomfortable feelings such as crawling, creeping, tingling, burning, or aching.
• The urge to move starts or gets worse when you are resting, sitting, or lying down.
• Moving your legs, walking, or stretching makes the feeling better, at least for a while.
• Symptoms are worse in the evening or at night.

Symptoms in children

• Children may have trouble describing the sensation and instead complain of 'growing pains' or restlessness.
• They may have difficulty falling asleep or staying asleep, leading to daytime sleepiness or irritability.
• Some children may be misdiagnosed with attention or hyperactivity problems.

Symptoms in older adults

• Symptoms may become more frequent and severe with age.
• Sleep can be seriously disrupted, causing significant daytime tiredness and reduced quality of life.
• Older adults may also have other medical conditions or take medications that can make RLS worse.

Causes

Main causes

• In many cases, the cause is not known. This is called primary or idiopathic RLS.
• Secondary RLS is caused by another condition, such as iron deficiency, kidney failure, nerve damage (neuropathy), or pregnancy.
• Some medications, including certain antidepressants, antihistamines, and antipsychotics, can trigger or worsen RLS.

Risk factors

• Having a family history of restless legs syndrome.
• Being middle-aged or older.
• Being female.
• Having low iron levels or anaemia.
• Having chronic diseases such as kidney disease, diabetes, or Parkinson’s disease.
• Pregnancy, especially in the third trimester.

When to see a doctor

See a doctor urgently if:

• If your symptoms are very severe, prevent you from sleeping, or cause extreme daytime tiredness.
• If you have numbness, weakness, or pain in your legs that is not relieved by moving them.
• If you suspect your symptoms might be caused by a medication you are taking.

Book a routine appointment if:

• If you have bothersome symptoms that happen regularly and affect your sleep or daily life.
• If you want to explore treatment options or need help with self-care strategies.
• If you have a family history and are concerned about developing RLS.

Diagnosis

There is no specific test for restless legs syndrome. Your doctor will diagnose it based on your symptoms, medical history, and a physical exam. They will ask you about when your symptoms happen, what makes them better or worse, and whether they affect your sleep.

Tests that may be done

• Blood tests to check your iron levels (ferritin), kidney function, and blood count.
• Sometimes a sleep study (polysomnography) may be done to check for other sleep disorders, but it is not usually needed for diagnosing RLS.
• Your doctor may also test for nerve damage or other conditions that can cause similar symptoms.

What to expect at your appointment

Your doctor will listen carefully to your description of the sensations and your urge to move. They may ask you to keep a symptom diary for a week or two. The diagnosis is usually straightforward based on the typical pattern of symptoms. If other conditions are suspected, you may be referred to a specialist such as a neurologist.

Treatment

Treatment aims to reduce symptoms, improve sleep, and improve your quality of life. Many people can manage mild RLS with lifestyle changes alone. If these are not enough, your doctor may recommend medications. The choice of treatment depends on how severe your symptoms are, your overall health, and whether you have any underlying conditions like iron deficiency.

Self-care at home

• Engage in moderate exercise during the day, such as walking, swimming, or cycling, but avoid vigorous exercise close to bedtime.
• Try leg stretches, massage, or warm baths before bed to relax your muscles.
• Apply heat or cold packs to your legs when symptoms start.
• Avoid or limit caffeine (coffee, tea, cola, chocolate), alcohol, and nicotine, especially in the evening.
• Establish a regular sleep schedule and make sure your bedroom is cool, dark, and quiet.
• If you feel the urge to move, get up and walk around or do gentle leg stretches until the feeling passes.

Medical treatments

If self-care is not enough, your doctor may prescribe medications. Common approaches include iron supplements if you are deficient, medications that affect dopamine (a brain chemical), or drugs that calm nerve activity. Some medications help reduce the unpleasant sensations and the urge to move. Your doctor will decide which treatment is safest and most effective for you. Treatment is always tailored to the individual, and you will be monitored for side effects.

When is surgery considered?

Surgery is not a treatment for restless legs syndrome. If you have severe symptoms that do not respond to other treatments, your doctor may discuss other options, but surgery is not part of standard care.

Living with this condition

Living with restless legs syndrome often means finding routines that help you manage symptoms. Many people learn to anticipate when symptoms are worse (such as in the evening) and plan relaxing activities or distractions. Keeping a symptom diary can help you identify triggers and what works best for you.

Lifestyle tips

• Stick to a consistent sleep schedule, even on weekends.
• Avoid heavy meals, caffeine, and alcohol late in the day.
• Find an activity that distracts you during restless periods, such as reading, listening to music, or doing a puzzle.
• Talk to your family and friends about your condition so they understand why you may need to move around.

Diet and exercise

A balanced diet rich in iron, folate, and magnesium may help some people. Foods like spinach, beans, fortified cereals, and lean red meat are good sources of iron. Regular, moderate exercise during the day can improve symptoms, but avoid intense exercise too close to bedtime. If you have iron deficiency, your doctor may recommend iron supplements.

Mental health and emotional wellbeing

Restless legs syndrome can cause significant anxiety and frustration, especially if it disrupts your sleep night after night. Poor sleep can lead to mood swings, irritability, and depression. If you feel overwhelmed, talk to your doctor or a mental health professional. If you are having thoughts of harming yourself, please contact your local crisis support service or call your local emergency number immediately.

Prevention

There is no sure way to prevent restless legs syndrome, especially if it runs in your family. However, you may be able to reduce your risk by avoiding known triggers such as too much caffeine, alcohol, or smoking. Keeping a healthy lifestyle with regular exercise and a balanced diet may help. If you have an underlying condition like iron deficiency, treating it can prevent or improve RLS symptoms.

Complications

If left untreated

• Chronic sleep loss, which can lead to daytime sleepiness, difficulty concentrating, and reduced work or school performance.
• Increased risk of anxiety, depression, and other mood disorders.
• Lower quality of life due to ongoing discomfort and disrupted sleep.
• Possible worsening of other health conditions like high blood pressure or heart disease due to poor sleep.

Long-term outlook

For most people, restless legs syndrome can be managed effectively with lifestyle changes and, when needed, medical treatment. Symptoms may come and go, but with the right approach, many people achieve good control and can sleep and function well. It is a chronic condition, but it does not cause permanent damage to your legs or shorten your life.
