Quick facts

When most common: 3rd trimester
Typical feel: Tingling, numbness or pain in thumb and fingers
Usual cause: Fluid retention pressing on the wrist nerve
Often worse: At night or first thing in the morning
Usually resolves: Within weeks of giving birth

Waking up with a numb, tingling or 'pins and needles' hand — especially in the thumb, index and middle fingers — is a surprisingly common complaint in later pregnancy. This is carpal tunnel syndrome, caused by the extra fluid your body holds onto pressing on a nerve as it passes through your wrist.

It can be uncomfortable and occasionally quite painful, but it's rarely a sign of anything serious and usually settles down after your baby is born. This guide explains why it happens, what eases it, and the rare occasions it's worth flagging to your doctor sooner.

What is carpal tunnel syndrome?

The carpal tunnel is a narrow passageway of bone and ligament on the palm side of your wrist, through which the median nerve and several tendons pass. When tissue in the tunnel swells — as commonly happens in pregnancy due to fluid retention — it compresses the nerve, causing tingling, numbness, aching or weakness in the thumb, index, middle and part of the ring finger.

Symptoms often start or worsen in the third trimester and are frequently worse at night or on waking, sometimes disturbing sleep. It can affect one or both hands, and gripping objects or fine movements like doing up buttons may become harder. For most people it improves within days to weeks of delivery as fluid retention resolves.

Not the same as general hand swelling

Some swelling of the hands is common and normal in pregnancy. Carpal tunnel syndrome specifically causes tingling or numbness along the nerve's pathway — the thumb and first two-and-a-half fingers — rather than just puffiness.

What causes carpal tunnel syndrome in pregnancy?

It's driven by the normal fluid and hormonal changes of pregnancy putting pressure on the nerve.

Fluid retention

Pregnancy causes your body to retain more fluid, which can build up in the tissues of the wrist and narrow the carpal tunnel.

Hormonal changes

Hormones that soften ligaments elsewhere in the body may also affect the tissues around the wrist, contributing to swelling and pressure.

Repetitive hand movements

Typing, using a phone, or repetitive tasks can add to nerve irritation, though they aren't usually the underlying cause in pregnancy.

Sleeping position

Sleeping with wrists bent can worsen symptoms overnight, which is why symptoms are often worst first thing in the morning.

Pre-existing risk

You may be more likely to develop carpal tunnel syndrome if you've had it before, or if you're carrying twins or more (more fluid retention).

Third trimester is peak time

Symptoms often become most noticeable in the last few months, when fluid retention is at its highest.

When carpal tunnel symptoms are typical

These features are consistent with ordinary pregnancy-related carpal tunnel syndrome:

Tingling, numbness or aching in the thumb and first two or three fingers, often both hands.
Symptoms that are worse at night or first thing in the morning and ease during the day.
Shaking your hand or changing position brings some relief.
No sudden, dramatic swelling elsewhere or other new symptoms.

	Usually typical carpal tunnel	Needs medical attention
Symptoms	Tingling/numbness in thumb & fingers	Sudden severe swelling of hands and face
Timing	Worse at night, gradual onset	Sudden onset with headache or visual changes
Other symptoms	None	Upper tummy pain, vomiting, severe headache
Grip	Mildly affected	Sudden marked weakness

It's very common and usually mild

Many people notice some tingling in the hands in the third trimester. For most, it's a nuisance rather than a serious problem.

Warning signs — get medical help now

Carpal tunnel symptoms alone are rarely an emergency, but sudden, severe hand swelling combined with other symptoms can point to pre-eclampsia. Contact your doctor or midwife urgently, or go to your nearest emergency department, if you have:

Seek urgent medical care if you have

Sudden or severe swelling of your hands, face or around your eyes.
A severe or persistent headache alongside the swelling.
Vision changes such as blurring, flashing lights or spots.
Pain just below your ribs, particularly on the right side.
Vomiting that's new or unusual for you in the second half of pregnancy.
A noticeable reduction in your baby's movements.

These combined symptoms can indicate pre-eclampsia, which needs prompt blood pressure and urine checks — don't wait for your next routine appointment.

Swelling plus headache or vision changes

This combination needs same-day assessment of your blood pressure and urine, as it can signal pre-eclampsia.

Self-care & relief for carpal tunnel syndrome

Simple changes can meaningfully ease day-to-day symptoms while your body carries the extra fluid.

Support your wrist

Wear a wrist splint at night to keep your wrist in a neutral position.
Avoid sleeping with your wrists tucked or bent underneath you.
Support your wrists when typing or using your phone for long periods.

Ease symptoms as they happen

Shake your hand out or dangle it over the side of the bed when it wakes you at night.
Gently stretch your wrist and fingers several times a day.
Run cool water over your wrists or use a cool compress if they feel swollen.

Reduce fluid build-up

Elevate your hands when resting where possible.
Reduce salty foods, which can worsen fluid retention.
Stay active with gentle movement to support circulation.

A physiotherapist or occupational therapist can help

If symptoms are persistent, ask about a referral for splinting advice or hand therapy.

When to consult a doctor

Arrange a non-urgent appointment if:

Numbness or weakness is affecting your grip or ability to do everyday tasks.
Symptoms are disturbing your sleep most nights despite trying a splint.
Pain or numbness is spreading beyond your hand, or affecting your whole arm.
Symptoms don't improve or are getting worse as pregnancy progresses.

Keep a symptom log

Noting when your hands are worst helps your doctor or midwife assess whether it's typical carpal tunnel syndrome or needs further review.

Frequently asked questions

Why do my hands go numb at night in pregnancy?

Fluid retention builds up in the wrist overnight and while you sleep with your wrists bent, compressing the nerve that runs through the carpal tunnel — this is why tingling and numbness are often worse first thing in the morning.

Will carpal tunnel syndrome go away after birth?

For most people, yes. Symptoms usually ease within days to a few weeks after delivery as your body loses the extra fluid it retained during pregnancy.

Do I need a wrist splint?

Many people find a night-time wrist splint, which keeps the wrist in a neutral position, significantly reduces symptoms. They're available over the counter, but ask your doctor or physiotherapist for advice on fit and type.

Can carpal tunnel syndrome affect my baby?

No, it's a nerve compression issue affecting you and doesn't affect your baby directly. It can, however, be uncomfortable enough to affect your sleep and daily tasks, which is worth addressing.

When should hand swelling worry me?

Sudden or severe swelling of your hands or face, especially with a headache, visual changes or upper tummy pain, needs same-day medical review, as this combination can indicate pre-eclampsia.

What's the difference between normal pregnancy swelling and carpal tunnel syndrome?

General swelling causes puffiness without necessarily affecting sensation, while carpal tunnel syndrome specifically causes tingling, numbness or pain along the nerve's path in the thumb and fingers.
