A Major Change For Restless Legs Treatment

Overview

Restless legs syndrome (RLS) is a condition that makes you feel a strong urge to move your legs, usually because of uncomfortable sensations like crawling, tingling, or aching. The feeling typically gets worse in the evening or at night, especially when you are sitting or lying down. Moving your legs usually eases the feeling for a short while. It is also called Willis–Ekbom disease.

Yes, restless legs syndrome is common. Around 1 in 10 people experience symptoms at some point in their lives. It can range from a mild annoyance to a condition that seriously disrupts sleep and daily life.

RLS can start at any age, but it becomes more common as people get older. It affects both men and women, though women are more likely to experience it, especially during pregnancy. It can also run in families.

Symptoms

Common symptoms

• A strong, hard-to-resist urge to move your legs, especially when resting or lying down.
• Uncomfortable feelings in the legs, such as crawling, pulling, throbbing, itching, or aching.
• Symptoms that get worse in the evening or at night.
• Temporary relief from moving, stretching, or walking.
• Difficulty falling asleep or staying asleep because of leg discomfort.

Symptoms in children

• Children may describe the feeling as 'bugs crawling' on their legs or say their legs 'feel funny.'
• They may seem restless or fidgety, especially at bedtime.
• They may have trouble falling asleep, which can affect their behaviour and concentration during the day.

Symptoms in older adults

• Symptoms may be more frequent and more intense with age.
• Sleep disturbances are often more noticeable and can lead to daytime tiredness.
• Older adults may also have other conditions or take medicines that can make RLS symptoms worse.

Causes

Main causes

• The exact cause is not fully understood, but it involves an imbalance of dopamine, a brain chemical that helps control movement.
• Low iron levels in the brain are now recognised as a major contributing factor, even when a blood test shows normal iron in the body.
• Genetics can play a role — RLS often runs in families.
• Pregnancy, especially in the third trimester, can trigger or worsen symptoms.
• Some chronic conditions like kidney failure or nerve damage can be linked to RLS.

Risk factors

• Having a family member with restless legs syndrome.
• Being middle-aged or older.
• Iron deficiency or anaemia.
• Pregnancy.
• Taking certain medicines (for example, some antidepressants, antihistamines, or antinausea drugs) — ask your doctor or pharmacist to review your medicines.
• Heavy alcohol use, smoking, or too much caffeine.
• Long periods of sitting or immobility.

When to see a doctor

See a doctor urgently if:

• If you have sudden leg pain, swelling, redness, or a feeling of warmth in one leg, seek urgent care — this could be a blood clot.
• If you have leg weakness or numbness that starts suddenly, especially with other warning signs like chest pain or confusion, call emergency services.

Book a routine appointment if:

• If the urge to move your legs happens often and makes it hard to relax, sit still, or sleep, make an appointment with your GP.
• If you feel tired during the day because of poor sleep, talk to your doctor.
• If you are pregnant and have leg symptoms that bother you, mention them to your midwife or doctor.

Diagnosis

Doctors diagnose restless legs syndrome by listening to your description of symptoms and asking about when they happen, how they feel, and what makes them better. There are no special tests to confirm RLS, but your doctor will make sure other conditions are not causing your symptoms.

Tests that may be done

• A blood test to check your iron levels (ferritin) — this is now considered a key step in the new approach to treatment.
• A physical examination to rule out nerve problems, joint issues, or circulation problems.
• In some cases, a sleep study may be suggested if your doctor suspects other sleep disorders.

What to expect at your appointment

Your doctor will ask questions about your sleep, daily routine, medicines, and family history. They may also review any medicines you are taking. You do not need any painful or invasive tests. After the appointment, your doctor may suggest keeping a symptom diary to track your triggers.

Treatment

The biggest change in restless legs treatment is this: iron is now checked and treated first, before other medicines are tried. Many people with RLS have low iron stores even if their blood count is normal. Replacing iron (if needed) can improve or even resolve symptoms. For others, treatment focuses on healthy sleep habits, gentle movement, and avoiding triggers. Medicines are only used when non-drug steps do not help enough.

Self-care at home

• Get regular, moderate exercise during the day — like walking, swimming, or yoga — but avoid very intense exercise late in the evening.
• Develop a calming bedtime routine, and go to bed and wake up at the same times.
• Avoid caffeine, alcohol, and tobacco, especially in the evening.
• Try stretching your legs or massaging them before bed.
• Apply warm or cool packs to your legs to ease discomfort.
• Take short walks or move your legs when symptoms start.

Medical treatments

Your doctor may recommend iron replacement if your blood tests show low iron levels. You should only take iron supplements under the supervision of a healthcare professional, because too much iron can be harmful. For people whose symptoms do not improve with iron and lifestyle changes, a doctor may prescribe other medicines that affect the brain's movement pathways, such as dopamine-based medicines or alpha-2-delta ligands. These options are tailored to your individual situation, and your doctor will explain the benefits and possible side effects. Remember, never start or stop any medicine for RLS without speaking to your doctor.

When is surgery considered?

Surgery is not a standard treatment for restless legs syndrome. It is not used to treat the condition itself. If you have a vein, nerve, or other structural problem that mimics RLS, your doctor will discuss any surgical options based on the specific condition, not for RLS as a whole.

Living with this condition

Living with RLS can be challenging, but most people find ways to manage. Keep a notebook of your symptoms — note what you ate, your sleep, your stress, and what made the symptoms better or worse. Share this with your doctor. Plan your day to include movement and time to wind down. If symptoms bother you during long meetings or car trips, stand up, stretch, or walk around when possible.

Lifestyle tips

• Take part in enjoyable physical activities that keep your legs moving gently.
• Try relaxation techniques like deep breathing, meditation, or mindfulness to reduce stress, which can trigger symptoms.
• Get natural light during the day, especially in the morning, to help regulate your body clock.
• Wear loose, comfortable clothing and avoid tight socks or stockings that can irritate your legs.
• If you have trouble sleeping, keep your bedroom cool, dark, and quiet.

Diet and exercise

Eat a balanced diet and make sure you are getting enough iron. Good sources include lean red meat, beans, lentils, tofu, and dark leafy greens. Pair iron-rich foods with vitamin C (like citrus fruits) to help absorption. Avoid tea and coffee right after meals, as they can block iron absorption. Regular exercise — like walking or cycling — can ease symptoms, but not too close to bedtime. Talk to your doctor before taking any iron supplements; you should not take iron without knowing your levels.

Mental health and emotional wellbeing

Living with uncomfortable leg sensations and broken sleep can affect your mood, energy, and concentration. It is normal to feel frustrated, anxious, or low at times. Be kind to yourself. RLS is not your fault. If you feel down or anxious most of the day, talk to your doctor — help is available, and supporting your mental health is part of managing RLS.

Prevention

There is no guaranteed way to prevent restless legs syndrome, especially when it runs in the family or occurs during pregnancy. However, you may be able to reduce the risk of symptoms by maintaining healthy iron levels, exercising regularly, avoiding alcohol and caffeine, and keeping good sleep habits. If you already have RLS, these steps may help prevent symptoms from getting worse.

Vaccines

There are no vaccines for restless legs syndrome. Keep your vaccinations up to date for your overall health — a sudden illness can sometimes make RLS symptoms more noticeable.

Screening programmes

If you have a family history of RLS, or if you have conditions like kidney disease, diabetes, or anaemia, it is worth asking your doctor if you should have your iron levels checked. There is no routine national screening programme for RLS, but testing can be done if you have symptoms.

Complications

If left untreated

• Chronic sleep deprivation, which can affect memory, concentration, and work performance.
• Higher levels of stress, anxiety, or depression due to ongoing discomfort and exhaustion.
• Difficulty sitting still for periods, which may interfere with travel, meetings, or social events.
• A reduced quality of life and reduced daytime energy.

Long-term outlook

There is every reason to be hopeful. The big change in treatment — focusing on iron levels first and using lifestyle changes early — has helped many people find real relief. Though RLS is a long-term condition for some, symptoms can often be controlled very well. With the right guidance from your doctor and a little patience, most people regain restful sleep and feel more in control of their body.
