Restless Legs Syndrome: who to see and what helps

Restless Legs Syndrome · Kitchener, Waterloo & Cambridge

Restless legs syndrome is a strong, hard-to-resist urge to move your legs that comes on at rest in the evening or at night and eases while you move. The most useful first step is a blood test for iron: the 2025 sleep medicine guideline says to check ferritin and transferrin saturation in everyone with significant symptoms, and sets its own thresholds for treating with iron. Testing and dosing iron belong to a physician or nurse practitioner, so at CARESPACE the place to start is a Nurse Practitioner, or a Naturopathic Doctor for sleep and triggers once iron has been checked.

What restless legs syndrome is

It is a disorder of sensation and movement. Uncomfortable feelings in the legs, and sometimes the arms, create an urge to move that is hard to resist, and moving relieves it for a while. It usually begins about 15 minutes after you lie down to sleep, or during a long spell of sitting still. Most people with it also have periodic limb movements: jerking leg movements during sleep that can disturb their own sleep and a bed partner’s.

Symptoms of restless legs syndrome

• An urge to move the legs that is very hard to ignore
• Tingling, prickling, crawling, throbbing or itching in the legs, and sometimes pain
• Symptoms that start or get worse at rest, and in the evening or at night
• Relief while you walk, stretch or move
• Broken sleep, for you and sometimes for the person beside you

The setting gives it away as much as the feeling: the last hour of a drive home along the 401, an evening flight, the second half of a movie.

What causes it

Usually no clear reason is found. It runs in families, and it is thought to be linked to iron levels and to dopamine, a chemical messenger in the brain. Sometimes there is a cause that can be treated:

• Low iron
• Pregnancy, especially after week 20; it usually goes away after the birth
• Kidney disease
• Other conditions it is linked with: diabetes, nerve damage, rheumatoid arthritis and Parkinson’s disease
• Medicines. The sleep medicine guideline names antihistamines and medicines that act on serotonin or block dopamine; HealthLink BC adds cold and sinus products. Do not stop a prescribed medicine on your own: ask your prescriber or pharmacist.
• Alcohol, caffeine and tobacco, and untreated sleep apnea

How it is diagnosed

From your description, which is why it helps to describe an evening and not just a daytime visit. A clinician looks for the pattern: an urge to move the legs that comes on at rest, is relieved by movement, and is worse in the evening or at night. Blood tests look for causes, iron above all, and nerve tests or a sleep study are sometimes added. Leg cramps and peripheral neuropathy can feel similar, so the pattern matters.

Restless legs syndrome has no emergency signs in the sources we read. See a physician or nurse practitioner if it is stopping you sleeping, affecting your mental health or your days, getting worse, or not responding to the self-help below.

What the evidence says about treating restless legs

• Where this comes from. The American Academy of Sleep Medicine’s 2025 guideline, a Cochrane review of iron and a systematic review of non-drug treatments. The guideline labels each recommendation strong or conditional and rates the certainty of the evidence separately; the strength reflects how confident the panel is, not only how good the studies are.
• Test iron first. The guideline’s advice to clinicians is to check ferritin and transferrin saturation in everyone with significant restless legs, ideally in the morning, after at least 24 hours without iron-containing supplements or foods. Its thresholds, set by expert consensus and not tested in trials, are iron by mouth or by vein at a ferritin of 75 ng/mL or below or a transferrin saturation under 20%, and intravenous iron only between 75 and 100.
• Iron probably helps. In the Cochrane review, iron probably improved restlessness and severity more than placebo: about 3.8 points on a 40-point severity scale (seven studies, 345 people, moderate certainty). Most of the review’s studies used intravenous iron, and not everyone in them had low iron to begin with. For people whose iron status calls for it, intravenous ferric carboxymaltose carries a strong recommendation and ferrous sulfate tablets a conditional one.
• Deal with what aggravates it. The first step is to address alcohol, caffeine, the medicines listed above and untreated sleep apnea.
• The first-choice medicines have changed. Gabapentin, gabapentin enacarbil and pregabalin each carry a strong recommendation. The guideline now recommends against the standard use of the dopamine medicines once given first (pramipexole, ropinirole, rotigotine, levodopa), because over time they can make restless legs worse, an effect called augmentation. These are conditional recommendations, with the remark that the medicines may still suit people who put short-term relief first; against cabergoline the recommendation is strong.
• Valerian is not recommended. The recommendation against it is conditional, on very low certainty evidence.
• Non-drug treatments are promising and thinly tested. A review of eleven trials reported that exercise, compression devices, a manual technique called counterstrain, infrared light, acupuncture and magnetic stimulation of the brain each reduced severity, and that vibration pads, cold therapy and electrical stimulation of the brain did not. Its authors’ own verdict: few studies, and evidence that was not of high quality.

What a physician or nurse practitioner provides

Iron tests, iron by tablet or infusion, prescriptions and changes to your other medicines are medical decisions, made with a physician or nurse practitioner. In pregnancy the guideline asks prescribers to weigh the safety of each treatment, and HealthLink BC says a doctor may recommend conservative treatment, such as regular exercise and stretching.

How each CARESPACE service helps with restless legs

Nurse Practitioner

Testing iron takes someone who can order blood tests and prescribe, and in Ontario Nurse Practitioners are authorized to do both, as well as to diagnose and to refer. For restless legs that covers the ferritin and transferrin saturation tests, a look through your medicines for ones that aggravate it, questions about sleep apnea, a decision about iron, and a prescription if symptoms call for one.

Naturopathic Medicine

Sleep is within a Naturopathic Doctor’s scope of practice, and most of the non-drug advice for restless legs is about sleep and triggers: regular bed and wake times, caffeine and alcohol, tobacco, the timing of meals and exercise. A Naturopathic Doctor can work through those with you. On products, the evidence sets limits. Iron should follow a blood test and a dose set by a physician or nurse practitioner, because the amounts that matter for restless legs are judged from ferritin and transferrin saturation. Valerian carries a recommendation against. Check any supplement with a pharmacist, physician or nurse practitioner first.

Physiotherapy

Exercise is one of the non-drug treatments that reduced severity in trials, and the amount seems to matter: HealthLink BC’s guidance is that regular, moderate exercise may reduce symptoms, while very intense workouts may make them worse. A physiotherapist can set up a moderate exercise program for the daytime, and show you stretches to use before bed and when symptoms start. Physiotherapists assess and treat at the first visit.

Other services people ask about

Massage Therapy. Massaging the legs is on both the NHS and HealthLink BC lists of things to try when symptoms start, but massage therapy is not among the treatments named in the summary of the review of trials, so we cannot say it has been tested. Acupuncture. The same review counts standard acupuncture among the treatments that reduced severity, with the caution about evidence quality noted above. Nutrition. The sources give no diet for restless legs beyond cutting back caffeine and alcohol. Where iron is low, the food side is covered on our Iron Deficiency page, but food alone is not how the guideline treats restless legs.

Where most people start

With a Nurse Practitioner or your own physician, because the first step is a blood test and a look at your medicines. A Naturopathic Doctor is the other place to start if your iron has already been checked and what you need is help with sleep and triggers. You leave a first visit with a plan.

How your team works together

Restless legs is mostly a one- or two-person job. The prescriber handles iron and any medicine; a Naturopathic Doctor or a physiotherapist handles the habits and the exercise.

Browse by service: nurse practitioners, naturopathic doctors and physiotherapists.

What to expect at your first visit

1. An evening, described. When it starts, what it feels like, what you do to settle it, and how much sleep it costs.
2. Family and history. Whether relatives have it, and any pregnancy, kidney disease, diabetes or anemia.
3. Everything you take, including antihistamines, cold remedies, sleep aids and supplements, plus caffeine and alcohol.
4. Earlier blood work, if you have it, with the actual ferritin number.
5. A plan to take home.

What you can do at home

• Exercise during the day, at a moderate level, and avoid hard workouts late in the evening.
• Keep the same bedtime and wake time and a dark, quiet, cool bedroom, and do not nap during the day.
• No caffeine after midday, and no alcohol for at least two hours before bed.
• If you smoke, get help to stop.
• Avoid large meals late in the evening and long spells of sitting.
• When symptoms start: walk, stretch or massage your legs; try a warm bath or a heating pad, or cold if that works better for you; and give your mind something to do, such as reading or a puzzle.

Outlook

The sources give no timeline for recovery. Mild symptoms may be controlled with lifestyle changes alone, symptoms linked to pregnancy usually go away after the birth, and treating an underlying cause such as low iron may help. HealthLink BC notes that symptoms often worsen with age.

Common questions

What ferritin level is too low for restless legs?

The sleep medicine guideline’s consensus threshold for considering iron is a ferritin of 75 ng/mL or below (the same number in µg/L), or a transferrin saturation under 20%. Those numbers are specific to restless legs, so ask for your actual result. Whether and how to take iron is a decision for a physician or nurse practitioner.

Does magnesium help restless legs?

Magnesium is not among the treatments the guideline’s summary recommends for or against, and neither the NHS nor HealthLink BC mentions it. We found no basis in these sources to recommend it.

Which medicines make restless legs worse?

Antihistamines, medicines that act on serotonin or block dopamine, and some cold and sinus products can. Some antidepressants help some people and worsen symptoms in others. Ask your prescriber or pharmacist before changing anything.

Is restless legs syndrome the same as leg cramps?

No, though the NHS notes that leg cramps and peripheral neuropathy can cause similar symptoms. What marks restless legs is the urge to move that comes on at rest and eases with movement.
