Restless Legs in Pregnancy: The Evening Urge to Move
Restless legs in pregnancy is common and more maddening than dangerous: a strong urge to move your legs that comes with a crawling, tugging or throbbing feeling. It shows up when you sit or lie still, usually in the evening, and moving brings relief for as long as you keep moving. It tends to get worse later in pregnancy and usually goes away after the birth. What helps is walking it off, slow stretches, a warm bath, massage and a calmer bedtime. If it’s costing you sleep, tell your OB or midwife, and ask whether your iron should be checked.
Where this post stops
I’m not a doctor or a midwife. I’m pregnant with my second, and this is the “is this normal-ish?” version, built from NHS, NCT, Cleveland Clinic, MedlinePlus and NIH pages I read in November 2026. If anything in the “when to call” section fits, skip the rest and call.
What restless legs feels like
The NHS restless legs syndrome page describes “a strong urge to move your legs, usually when resting at night”. The NIH’s NINDS restless legs page says it can feel like “aching, throbbing, pulling, itching, crawling, or creeping”. Three things set it apart:
- It starts when you stop. MedlinePlus says the feelings “start or get worse when you lie down or sit for long periods of time”.
- Moving fixes it, briefly. NINDS says walking typically brings relief, “but the sensations often return as soon as movement ceases.”
- It keeps evening hours. NINDS says symptoms commonly come “in the late afternoon or evening hours”. That’s exactly when you finally sit down after the toddler’s bedtime.
NINDS adds that most people with restless legs also twitch in their sleep, every 15 to 40 seconds. You won’t feel it, but whoever sleeps next to you might.
Why pregnancy sets it off
The NCT’s page on sleep disruption in pregnancy says up to 1 in 4 pregnant women and people get it, about 2 in 3 of them for the first time, and that it usually gets worse toward the end. Cleveland Clinic’s restless legs overview says the risk “increases with each trimester”.
Nobody knows exactly why. The NHS says it’s “thought to be linked to the levels of iron and the brain chemical dopamine”, and that it runs in families.
This one matters if it’s your second. A Cleveland Clinic article on sleep during pregnancy says “once RLS shows up, it is more likely to recur in later pregnancies.” If you had it with your first, plan for it now. The other second-time changes are in second pregnancy differences.
Restless legs or a leg cramp?
Both wreck your nights and both live in your calves, but they need different fixes. Our post on leg cramps during pregnancy covers the cramp side.
| Leg cramp | Restless legs | |
|---|---|---|
| What happens | A muscle locks tight with a sudden pain | An urge to move, with crawly or tugging feelings |
| When | Any time, but mostly at night or at rest, and it can wake you (NHS) | Builds while you’re sitting or lying still, usually in the evening |
| How long | Seconds to about 10 minutes (NHS) | Can last an hour or longer (MedlinePlus) |
| What helps | Stretching that one muscle until it lets go | Moving, which helps only while you keep moving |
If you can’t tell which you have, describe it to your provider in your own words. “Crawling, and I have to get up” is a different story from “it locked and I couldn’t move it.”
What helps in the moment
- Get up and walk it off. Cleveland Clinic’s home remedies article says short bursts work, “like walking around the room or flexing and extending your legs.” A slow lap of the hallway counts.
- Stretch slowly. The same article says “slow, gentle and controlled stretches often work best”, and that “intense and bouncy” ones can make things worse.
- Rub your legs. The NHS suggests massage when symptoms hit. A partner can take the calves while you lie on your side.
- Try warm, then cold. NINDS lists a heating pad or an ice pack. Cleveland Clinic says to try both, adding that “most people have better results with warmth.” A pad with auto shut-off, like the Sunbeam XL heating pad, suits the evening sofa; switch it off before you sleep. If cold works better, a soft gel pack such as FlexiKold drapes over a calf.
- Give your brain a job. The NHS suggests “reading or doing a game or puzzle”, and Cleveland Clinic suggests a crossword.
Pacing the hallway at 10pm? Use the lap to plan the newborn nights
Betteroo turns a two-minute quiz into a day-by-day newborn sleep plan that adjusts as your baby changes. Take it while you're still pregnant, and the plan is ready before the first night home.

An evening routine that may calm it down
- A warm bath or leg soak before bed. It’s on the NHS, MedlinePlus and Cleveland Clinic lists.
- Move in the day, not late at night. The NHS says exercise during the day, and no strenuous exercise or big meal late at night. If your provider has told you to limit activity, follow that.
- Cut caffeine earlier. The NHS says none after midday, and NINDS names caffeine as a trigger.
- Keep bedtime regular. The NHS says same bedtime and wake time, a dark, quiet room, and no screens right before bed.
- Rest without dozing. The NHS says not to nap in the day, a big ask in pregnancy. NCT points out that rest “doesn’t all have to be sleep”, so feet up on the sofa, awake, still counts.
The side-sleeping setup is in how to sleep when pregnant. One tweak for restless legs: take the side of the bed nearest the door, so a lap doesn’t mean climbing over anyone.
Mention anything you already take. Cleveland Clinic says some antihistamines, anti-nausea medicines and antidepressants can make restless legs worse. Tell whoever prescribed yours, and don’t stop anything on your own. NCT says there isn’t enough data on whether the usual restless legs drugs are safe in pregnancy, so they aren’t recommended, and anyone already on one should discuss it with their doctor.
If you share a bed
NCT suggests separate covers, or sleeping apart for a while if that’s possible. Neither is a verdict on the relationship, and a partner who sleeps well can take the toddler’s early mornings.
Treat it as a rehearsal. Soon you’ll be passing nights back and forth anyway, and Betteroo’s guide to how couples divide the newborn nights is worth reading together now.
When to call your OB or midwife
Call your OB or midwife right away if one leg is swollen, red, warm or tender, or hurts constantly when you stand or walk. That isn’t restless legs. ACOG’s deep vein thrombosis FAQ lists those as signs of a blood clot in the leg, names pregnancy as a risk factor, and says it’s important to find and treat a clot early. Go to the emergency room or call 911 for sudden shortness of breath or chest pain. ACOG lists those as signs of a clot in the lungs.
Mention it at your next appointment, or call sooner, if:
- it’s stopping you from sleeping (NHS, MedlinePlus)
- it’s affecting your mood or mental health (NHS)
- you’ve tried the things above and they haven’t helped (NHS)
- it’s getting worse (MedlinePlus), or it comes several times a week and is affecting your sleep and daily life (Cleveland Clinic)
Ask about testing. MedlinePlus says your provider may order blood tests “to look for iron deficiency anemia”. Cleveland Clinic says testing matters because low iron “can be present even without obvious anemia.” Ask whether your iron should be checked; what follows a result is your provider’s call.
FAQ: restless legs in pregnancy
Will it go away after the baby comes?
Usually, yes. The NHS says pregnancy-linked symptoms “usually go away after giving birth”, and NCT says the same.
Is restless legs harmful to the baby?
None of the pages I read links restless legs itself to harm to the baby. The real cost is your sleep, and broken sleep on top of pregnancy fatigue is reason enough to raise it.
What can I do with the nights I’m up anyway?
Plan the next set. Betteroo builds a newborn sleep plan from a short quiz, for about $20 a month. It’s a planning tool, not medical advice.
