Carpal Tunnel in Pregnancy: Numb Hands at Night, What Helps

Carpal tunnel in pregnancy is common, and it’s usually worst at night. The extra fluid pregnancy brings can swell the narrow passage in your wrist and squeeze the nerve that runs through it. That gives you tingling, numbness or an ache in your thumb and first few fingers, often enough to wake you. What helps most is keeping your wrists straight while you sleep. A night wrist splint does that, and so do a few changes to how you lie. It usually settles after the birth. Weakness, dropping things or numbness that never wears off is a reason to call, not to cope.

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. It’s built from NHS, Cleveland Clinic, MedlinePlus and US Office on Women’s Health pages I read in October 2026. If anything in the “when to call” section fits you, skip the rest and call.

Why your hands go numb at night

The carpal tunnel is a narrow space in your wrist, near the base of your hand and thumb. A nerve called the median nerve runs through it. MedlinePlus’s carpal tunnel page says “any swelling can pinch the nerve”, and it lists “extra fluids retained during pregnancy” as one cause. The NHS carpal tunnel syndrome page names being pregnant as a risk factor.

The pregnancy version follows the swelling. An NHS Tayside physiotherapy page on carpal tunnel during pregnancy says mild swelling in the hands and wrists is common “usually from about 5 months”. Whittington Health’s NHS leaflet on carpal tunnel syndrome in pregnancy says symptoms “most often start in the third trimester”.

Night is when you notice it. The NHS says symptoms are “usually worse at night”. Cleveland Clinic’s carpal tunnel overview says people usually notice them first at night, when “pain or tingling may wake you up”. How you lie probably plays a part too. In late pregnancy you’re on your side all night, often with one arm folded under the pillow and the wrist bent.

What it feels like

Pins and needles, tingling or burning in the thumb, index and middle fingers and the thumb side of the ring finger (MedlinePlus, Tayside).
Numbness, which Cleveland Clinic says can feel as if your hands “fell asleep”.
An ache in the hand that can run into the wrist and forearm.
A weaker grip, especially in the thumb, so a mug, a pen or a shirt button gets harder to manage.

Tayside says it’s often worse “at night or first thing in the morning”. It can be one hand or both.

Sleep with your wrists straight

Keeping the wrist straight is the main fix. Cleveland Clinic calls it holding your wrist “in a neutral position to take pressure off your median nerve”. Whittington’s version is “try not to bend your wrist too much forward or backward.”

Wear a night splint. The NHS says to wear it at night, and that “you may need to wear a splint for up to 6 weeks before it starts to feel better.” You can buy one from a pharmacy or online. If you’d like it fitted properly, ask at your next prenatal appointment. The Office on Women’s Health body changes page suggests asking your doctor “about fitting you for a splint to keep wrists straight”. Whittington says a physiotherapist can supply one.

The worked example is the FUTURO Night Wrist Support. It’s a soft, adjustable sleeve that fits either hand, made for nighttime carpal tunnel symptoms. If both hands are affected, you’ll need one for each.

Change how you lie. Tayside’s advice is to “try not to sleep on your hands”, and to shift position whenever you feel the twinges. In a side-sleeping setup, that means:

Bring the lower arm out in front of you instead of folding it under the pillow or your cheek.
Rest the upper arm on a pillow, or on the top of your bump pillow, so the wrist lies flat rather than hanging down.
Keep both hands open and loose. A fist curled up under your chin is the wrist bend you’re trying to avoid.

Your bump pillow, knee pillow and back support all stay where they are. That setup is in how to sleep when pregnant.

When it wakes you anyway, Tayside says to “move your hands lightly until the pain or numbness reduces”, then shift position. Then put the splint back on.

Daytime habits that make nights easier

From the NHS physio leaflets:

Take your rings off if your fingers are starting to swell (Whittington).
Rest your hands up in the evening, on a cushion or along the back of the sofa (Tayside).
Cool them down. Tayside suggests resting your hands in cold water for a minute, then out for a minute, several times. Whittington suggests switching between cold and warm water. Whittington also says that if you can’t feel the cold on your skin, you should tell your health professional.
Pace the hand-heavy jobs. Tayside names cleaning, ironing and driving, and says to avoid heavy lifting.
Straighten your desk. Whittington says to set your chair so your wrists stay straight while you type. The rest of the desk setup is in working while pregnant.

If the ache needs more than this, ask your midwife, doctor or pharmacist what’s safe to take, and tell the pharmacist you’re pregnant.

When to call your OB or midwife

Call 911 straight away for sudden numbness or weakness in one arm or down one side of your body, especially with a drooping face or slurred speech. The NHS stroke symptoms page lists these as stroke signs, and says to get help even if they stop. That’s a different thing from slow-building tingling in both hands.

Call your maternity unit, OB or midwife urgently for sudden swelling in your face, hands or feet, especially with a severe headache, blurred vision or flashing lights, pain below your ribs, or vomiting. The NHS swelling in pregnancy page says a sudden increase in swelling “can be a sign of pre-eclampsia”. ACOG’s preeclampsia FAQ lists swelling of the face or hands and says to “call your ob-gyn right away”. Slow, gradual swelling is the ordinary kind. The general swelling picture is in third trimester comfort.

Bring it up at your next appointment, or call sooner, if:

you’re dropping things or your hand feels clumsy (MedlinePlus)
your grip or thumb is getting weaker
the numbness doesn’t wear off during the day
the splint and the changes above aren’t helping, or it’s getting worse (NHS)

Cleveland Clinic says not to brush these off: carpal tunnel “can cause permanent nerve damage if it’s not treated soon enough”, and it’s also “very treatable”. Your provider can confirm it’s carpal tunnel and talk you through the next options if a splint isn’t enough.

FAQ: carpal tunnel in pregnancy

When does carpal tunnel start in pregnancy?

It can start any time. Whittington says it’s most common in the third trimester, and Tayside says the swelling behind it usually begins from about 5 months.

Does it go away after the baby is born?

Usually. The Office on Women’s Health says symptoms “should disappear after delivery”. Whittington says they usually get better about six weeks after the birth. They can carry on while you’re breastfeeding, and occasionally for 6 to 12 months. If they last beyond six weeks, it says to see your doctor.

Should I wear a splint during the day too?

Start with nights. Whittington and MedlinePlus both suggest adding daytime wear if symptoms are bad or night splinting isn’t enough. Ask whoever fits it how long to wear it.

What can I do with the nights while I wait it out?

Plan for the next set of broken nights. Betteroo builds a newborn sleep plan from a short quiz, for about $20 a month. If you want something lighter, its week-24 symptom roundup lists numb hands alongside the other mid-pregnancy surprises. It’s a planning tool, not medical advice.
