Restless Legs Syndrome

Restless legs syndrome (RLS) is a nervous-system condition that causes an urge to move the legs, mostly when you rest in the evening or at night, and it can wreck your sleep. Low iron, kidney disease, pregnancy and some common medicines can play a part, so a check-up and a blood test come first. Good help exists, from iron and everyday habits to prescription medicines and devices, and some older medicines now carry a caution.

RLS itself is rarely an emergency, but get help right away for any of these:

What is restless legs syndrome?

RLS, also called Willis-Ekbom disease, is a neurological condition that causes an irresistible urge to move the legs, with feelings that can be aching, throbbing, pulling, itching or crawling. Symptoms start when you are resting, ease with movement, and are worse at night with a symptom-free stretch in the early morning (NINDS). The NHS notes that leg cramps and peripheral neuropathy can look similar (NHS), which is one reason to get checked rather than guess.

RLS can make it hard to fall or stay asleep, and can bring exhaustion, daytime sleepiness, trouble concentrating, depression and anxiety. Most people with RLS also have periodic limb movements of sleep, repeated leg twitching during sleep (NINDS). MedlinePlus Genetics estimates RLS affects 5 to 10 percent of U.S. adults and 2 to 4 percent of children, women more often than men (MedlinePlus Genetics); a 2026 JAMA review puts clinically significant RLS at about 3% of adults (JAMA review, 2026). Symptoms can come and go, with quiet stretches of weeks or months, but often return and may grow stronger over time (NINDS).

Primary and secondary RLS

Primary (idiopathic) RLS has no identified underlying condition and is strongly influenced by genes. Secondary RLS is caused by another condition, such as end-stage kidney disease or peripheral neuropathy (review, 2014). In most cases the cause is unknown (NINDS), and 40 to 90 percent of affected people report an affected parent or sibling (MedlinePlus Genetics). Low iron in parts of the brain and a problem with the brain chemical dopamine are thought to be involved (NINDS).

Medicines and substances that can make it worse

Some anti-nausea medicines, antipsychotics, antidepressants that raise serotonin and some antihistamines can aggravate RLS (NINDS). MedlinePlus Genetics adds certain medicines for colds and allergies, heart problems and high blood pressure, and says caffeine, nicotine and alcohol can trigger or worsen symptoms (MedlinePlus Genetics). The American Academy of Sleep Medicine (AASM) says the first step is addressing these factors, including antihistamine, serotonin-acting and dopamine-blocking medicines and untreated sleep apnea (AASM guideline, 2025). Please don’t stop or change a prescribed medicine on your own. Bring your full list, including over-the-counter sleep, cold and allergy products, to your prescriber or pharmacist. See Medication Safety.

Getting checked

There is no specific test for RLS. A provider reviews your symptoms, history and medicines, and blood tests can rule out kidney failure, low iron and other causes (NINDS). An overnight sleep study is not recommended to diagnose it (JAMA review, 2026). The AASM says everyone with clinically significant RLS should have iron studies, including ferritin and transferrin saturation, ideally in the morning and without iron-containing supplements or foods for 24 hours beforehand (AASM guideline, 2025). Ferritin is a protein that stores iron (MedlinePlus). The guideline’s iron cut-offs are consensus-based, differ from those for the general population, and have not been empirically tested, so ask your clinician how your numbers apply to RLS.

When to see a clinician: if RLS is stopping you from sleeping, affecting your mood, or hasn’t improved with self-help (NHS). Also go for severe daytime sleepiness, if symptoms start or worsen in pregnancy, or if a medicine may be the trigger. If you already take an RLS medicine, call your prescriber if symptoms begin earlier in the day or grow stronger, which can be a sign of augmentation (explained below) (FDA label). In children RLS can be misread as “growing pains” or ADHD, so describe the leg feelings and the night pattern (NINDS).

Side by side

Six approaches compared

For every condition we look at the same six approaches: what each involves, what it typically costs, and what a patient can realistically expect.

ApproachWhat it involves Estimated costWhat to expect
Conventional medicine (AMA) Checking medicines and other conditions, blood tests for iron, iron treatment when levels call for it, prescription medicines (gabapentinoids are now first in line for most people), prescription devices, and special care in pregnancy and kidney disease. Cost estimate being researched. Treatment can help manage symptoms but is not a cure. Iron probably helps when levels are low. Older dopamine-agonist medicines can work at first, then make RLS worse over time (augmentation), so guidelines have moved away from them.
Chiropractic No established role for RLS itself. A chiropractor may notice RLS, rule out look-alike back or leg problems, and refer you for a blood test. About $55–$100 for a self-pay follow-up visit and $90–$200 for a first visit. Medicare Part B covers only certain chiropractic services. We found no controlled studies of chiropractic adjustment for RLS, only a single case report. Serious side effects of spinal manipulation are very rare.
Acupuncture Needle sessions on leg and body points, alongside — not instead of — checking iron and medicines. About $125–$230 for a first private visit and $90–$185 for follow-ups; community clinics about $50–$90. Medicare covers acupuncture only for chronic low back pain. Evidence is mixed: a Cochrane review found too little to judge, while later reviews of low-quality studies suggest benefit. Few complications are reported with a trained, licensed practitioner.
Herbal medicine Magnesium, vitamins C, E, B6 and D, valerian and Chinese herbal formulas. Iron is a supplement too, but it should follow a blood test. Cost estimate being researched. Evidence is limited and often low quality. The AASM suggests against valerian, and a vitamin D trial found no benefit. Don’t take iron without checking your levels.
Massage therapy Leg massage and relaxation bodywork, used alongside medical care. About $70–$90 a month for a membership at one national chain (Massage Envy), which includes one 60-minute session a month; each franchise sets its own rates. Medicare does not cover massage therapy. Health agencies list leg massage as something to try. Small reviews in people on hemodialysis suggest it can lower RLS severity; we found less evidence for everyone else.
MBHA Wellness Coach Steady sleep times, regular moderate exercise, less caffeine, alcohol and nicotine, warm baths or heat and cold, mentally absorbing activities in the evening, a symptom and medicine diary, and help preparing for doctor visits. Cost estimate being researched. Health agencies recommend these habits as first steps, and exercise has some research support. Habits help but do not replace a check for iron, kidney disease or medicine triggers.

Approach 1 of 6

Conventional medicine (AMA)

NINDS puts it plainly: RLS has no cure, but treatment can help manage symptoms, and the first step is to address anything that could be making it worse (NINDS). Medicine advice has changed a lot recently. The AASM’s 2025 guideline rests on a systematic review in which 148 of 3,631 studies had data suitable for analysis (AASM systematic review, 2025). We name medicines only to explain the evidence and label warnings; your prescriber chooses what fits you, and we list no doses.

1. Fix what can be fixed

That means treating conditions such as diabetes, neuropathy, sleep apnea or iron deficiency, and cutting back on alcohol, nicotine and caffeine (NINDS). A 2026 JAMA review also says that, if possible, medicines linked with RLS should be discontinued, naming serotonin-acting antidepressants, dopamine blockers and sedating antihistamines such as diphenhydramine (JAMA review, 2026). Whether that is possible for you is a decision for you and your prescriber.

2. Iron

  • The AASM consensus statement suggests oral or intravenous (IV) iron in adults with serum ferritin at or below 75 ng/mL or transferrin saturation below 20%, and IV iron only when ferritin is 75 to 100 ng/mL. For children the ferritin cut-off is under 50 ng/mL (AASM guideline, 2025).
  • A Cochrane review of 10 trials (428 people) found iron probably improves restlessness and RLS severity compared with placebo (moderate certainty), did not cause significantly more side effects than placebo, and left the effect on quality of life uncertain (Cochrane review, 2019).
  • The AASM strongly recommends IV ferric carboxymaltose in people with appropriate iron status and conditionally suggests ferrous sulfate and other IV irons (AASM guideline, 2025).
  • Test first. Too much iron, like too little, can cause serious health problems (MedlinePlus). The NHS says people with low iron may need iron supplements (NHS); that is a decision to make after a blood test.

3. Gabapentinoids (alpha-2-delta ligands)

The AASM strongly recommends gabapentin enacarbil, gabapentin and pregabalin for adults with RLS, each with moderate-certainty evidence (AASM guideline, 2025). The JAMA review calls them first-line and reports that in trials about 70% of people on a gabapentinoid were much or very much improved, versus about 40% on placebo (JAMA review, 2026). The Horizant (gabapentin enacarbil) label states an approval for moderate-to-severe primary RLS in adults. Its warnings include significant driving impairment; sleepiness (20% versus 6% on placebo in the RLS trials) and dizziness (13% versus 4%); dangerously slowed breathing when combined with other sedating medicines such as opioids; possible suicidal thoughts, as with other medicines in its class; and seizures or withdrawal symptoms if stopped abruptly (FDA label). Never stop one suddenly on your own.

4. Dopamine-acting medicines and augmentation

For years, dopamine agonists such as pramipexole, ropinirole and rotigotine were the usual first choice, and the 2016 American Academy of Neurology guideline gave several its strongest evidence rating while saying augmentation risk should be considered (AAN guideline, 2016). Augmentation is the problem. The rotigotine (Neupro) label defines it as a worsening of RLS during treatment, with more severe symptoms or symptoms that start earlier each day, and says dopamine-acting medicines can cause it (FDA label). After ten years of experience since its 2012 guideline, the AASM concluded these medicines may help in the short term but can make RLS worse over time (AASM plain-language summary, 2025).

  • Its 2025 guideline suggests against the standard use of levodopa, pramipexole, rotigotine and ropinirole (conditional), while noting one may still suit someone who values short-term relief and accepts a higher risk of augmentation; it recommends against cabergoline (strong) (AASM guideline, 2025). The JAMA review puts augmentation at 7% to 10% of patients a year (JAMA review, 2026).
  • Not everyone agrees: in a World Sleep Society survey, 23 of 53 national sleep societies responded, and avoiding dopaminergic agents “generated regional disagreement” (World Sleep Society survey, 2025).
  • The Neupro label also warns about falling asleep during daily activities, including driving, and about intense urges such as gambling, spending or binge eating (FDA label).

If you already take one and it has helped, don’t stop it yourself; ask your prescriber about the plan. People with augmentation often benefit from other treatment (JAMA review, 2026).

5. Other medicines

NINDS reserves opioids for severe RLS that does not respond to other treatments (NINDS); the AASM conditionally suggests extended-release oxycodone and other opioids, and suggests against bupropion, carbamazepine, clonazepam, valerian and valproic acid (AASM guideline, 2025).

6. Prescription devices

What it costs

Cost estimate being researched for blood tests, prescription medicines and devices. Ask your plan what is covered before you start.

How well it works — what to expect

Many people improve with the right plan, but expect some trial and error, and symptoms may return (NINDS). If a medicine stops working or RLS gets worse, tell your prescriber rather than adding something on your own.

Approach 2 of 6

Chiropractic

Chiropractic care has no established role in treating restless legs syndrome. We found little research. The one chiropractic item was a 2008 case report: a 42-year-old man saw a chiropractor with leg symptoms that fit RLS and was reported 65% better in a month. A single case cannot show chiropractic care was the reason, and the report’s own conclusion was that practitioners need to recognize and diagnose RLS (case report, 2008).

A 2020 scoping review of 24 studies of manual therapy, exercise and other non-drug approaches found the clearest effects for exercise, acupuncture, pneumatic compression and near-infrared light; its abstract does not single out spinal adjustment (scoping review, 2020). A 2019 review counted “counterstrain manipulation,” a type of manipulation, among options that beat control conditions, with evidence not of high quality (systematic review, 2019). We read only the abstracts.

A chiropractor can be a second pair of eyes: leg cramps and nerve problems can look like RLS (NHS), so a good practitioner will ask about the evening pattern and refer you for a medical check, including iron tests.

Safety

Spinal manipulation commonly causes temporary soreness or stiffness; very rare serious problems, including strokes involving neck arteries, have been reported (NCCIH).

What it costs

About $55–$100 for a self-pay follow-up visit and $90–$200 for a first appointment (The Pricer). Medicare Part B covers only certain chiropractic services; after the deductible you pay 20% (Medicare.gov).

Approach 3 of 6

Acupuncture

Acupuncture is among the most studied non-drug options for RLS, but the evidence is mixed and mostly low quality.

What the research says

Our read: promising, not proven. If you try it, use it alongside — not instead of — an iron check and a medicine review.

Safety

Relatively few complications are reported, but they have come from non-sterile needles and improper technique and can include infections, punctured organs and nervous-system injury. The FDA requires acupuncture needles to be sterile and single-use (NCCIH).

What it costs

Private sessions run about $125–$230 for a first visit and $90–$185 for follow-ups; community clinics charge about $50–$90 (The Pricer). Medicare Part B covers acupuncture only for chronic low back pain (Medicare.gov).

Approach 4 of 6

Herbal medicine

Evidence for supplements is thin and often from small or low-quality studies. We list no doses.

Iron: the one to test for first

Iron has the best evidence, but it is meant for people whose blood tests call for it (see conventional medicine). Too much iron can be harmful, just like too little (MedlinePlus).

Magnesium

A 2019 systematic review found eight relevant studies, only one a randomized trial, which found no significant benefit but may have been underpowered; the authors could not conclude whether magnesium helps (systematic review, 2019). A 2024 review of 10 randomized trials (482 people) reported that magnesium oxide and vitamin B6 improved RLS symptoms and sleep quality, but half the studies had a high risk of bias (systematic review, 2024).

Vitamins C, E and D

Valerian and Chinese herbal formulas

The AASM conditionally suggests against valerian for RLS (very low certainty evidence) (AASM guideline, 2025). NCCIH says not to combine valerian with alcohol or sedatives (NCCIH), which matters if you take a sedating RLS medicine. A 2019 meta-analysis of 12 trials (639 people) found improvements with formulas containing Paeoniae Radix, but study quality was low and firm conclusions were not possible; its abstract calls the herbs relatively safe, and we did not read the full text (meta-analysis, 2019).

Before you try any herb or supplement, talk with your doctor or pharmacist, especially if you take other medicines, have kidney disease, or are pregnant. Some herbs and medicines interact in harmful ways (NCCIH).

Approach 5 of 6

Massage therapy

Leg massage is on the self-care lists of both NINDS and the NHS (NINDS, NHS). A trained therapist can do more, and some research supports it.

What the research says

Most of this research is in people on dialysis, so we can’t be sure it applies to everyone else. We read only the abstracts.

Safety

The risk of harm appears low, though rare serious problems, such as a blood clot, nerve injury or bone fracture, have been reported, sometimes with vigorous deep-tissue massage or in frail older adults (NCCIH). If one leg is swollen, red or painful, get it checked before any leg massage (MedlinePlus).

What it costs

One national chain, Massage Envy, charges about $70–$90 a month for a 12-month membership that includes one 60-minute session a month; each franchise sets its own rates (The Pricer). Medicare doesn’t cover massage therapy (Medicare.gov). Independent therapists: cost estimate being researched.

Approach 6 of 6

MBHA Wellness Coach

MedlinePlus says regular sleep habits, relaxation and moderate daytime exercise can help, and that caffeine, tobacco and alcohol may make symptoms worse (MedlinePlus). An MBHA Wellness Coach can help you build these habits, keep track of what helps, and prepare for the visits that matter. Habits support — but don’t replace — a check for iron, kidney problems and medicine triggers.

Move your body, at the right time

Evening routine

Keep a simple record

A coach can help you note when symptoms start each evening, caffeine, alcohol and nicotine use, and every medicine and supplement you take, so your clinician can spot triggers and augmentation early. Before iron tests, avoid iron-containing supplements and foods for 24 hours if your clinician asks (AASM guideline, 2025). RLS can bring depression and anxiety (NINDS), and the NHS says talking therapies may help (NHS); see Anxiety and Depression.

Another approach

Magnets and infrared products: what we found

RLS is exhausting, so it is natural to look at magnetic and infrared products. Here is what we found.

  • Magnets. NCCIH says research on static magnets (jewelry, mats, pillows, bed pads) is extremely limited and has found no conclusive evidence they work for any form of pain; that fact sheet covers pain, not RLS. We found little research on magnets for RLS: what came up was about transcranial magnetic stimulation, a clinic procedure that is not a magnet you wear or sleep on. NCCIH also cautions that magnets can interfere with pacemakers and insulin pumps and can be deadly if children swallow them (NCCIH).
  • Near-infrared light. A trial of 34 volunteers gave twelve 30-minute treatments to the lower legs over 4 weeks, and the treated group improved more than controls (randomized trial, 2011). In 60 people on hemodialysis, near-infrared light on leg and foot acupoints lowered RLS scores versus sham while in use, but the difference was no longer clinically meaningful after treatment stopped (randomized trial, 2018). A 2016 review judged the evidence insufficient (review, 2016).
  • Far-infrared blankets, pads or clothing. We found little research. The studies above used specific treatment devices, so they don’t show consumer far-infrared products help RLS. See Magnet Therapy and Sleep Problems.

Low-risk comforts are fine to enjoy, but don’t let a product delay the iron check, a medicine review or care for pain, swelling or sleepiness.

Another approach

RLS with kidney disease or dialysis

RLS is common with end-stage kidney disease and hemodialysis (NINDS). For this group the AASM conditionally suggests gabapentin, IV iron sucrose when ferritin is under 200 ng/mL and transferrin saturation under 20%, and vitamin C, and suggests against the standard use of levodopa and rotigotine (AASM guideline, 2025). A 2022 network meta-analysis of 24 trials (1,252 people on dialysis) found cool dialysate gave the largest drop in RLS severity, with high confidence; stretching during dialysis and aromatherapy massage looked promising with limited confidence; and gabapentin was the most effective medicine (network meta-analysis, 2022). Kidney disease changes how the body handles medicines and supplements, so please don’t add any on your own. See Dialysis.

Another approach

Pregnancy and children (brief)

Pregnancy. RLS has been found in about 10 to 34% of pregnant women, typically clearing soon after delivery; low iron and ferritin, high estrogen and family history may play roles (review, 2016). No standard RLS medicine for pregnancy is established, so relief is weighed against risks to mother and baby (review, 2014), and the AASM tells prescribers to consider each treatment’s pregnancy safety (AASM guideline, 2025). Tell your prenatal provider about leg symptoms and don’t start supplements or medicines on your own. See Female Problems.

Children. RLS is hard to diagnose in children, who struggle to describe it (NINDS). The AASM conditionally suggests ferrous sulfate for children with appropriate iron status (AASM guideline, 2025); a pediatric clinician should guide treatment.

Another approach

Putting the six approaches together

For most people the best-supported path is a medical check first: review medicines, look for iron deficiency, kidney disease, neuropathy and sleep apnea, then choose among iron, a gabapentinoid and, for some, a device (AASM guideline, 2025, JAMA review, 2026). Wellness coaching supports the daily habits health agencies list. Massage and acupuncture may add comfort, with honest limits on the evidence. Herbs and supplements deserve caution, and iron should follow a blood test. Chiropractic has no established role for RLS itself. Please don’t stop or change a prescribed medicine without talking with your prescriber.
