Wrist and thumb pain in new mothers (De Quervain's)

Two tendons that move the thumb run through a narrow tunnel at the wrist. Lifting a baby with the hand spread in an L shape, thumb pointing up, puts these tendons under repeated strain. Hormonal changes after pregnancy and during breastfeeding are also thought to play a part.

Pain usually starts a few weeks after delivery, at the base of the thumb and side of the wrist. It is worse when lifting the baby, wringing clothes, opening jars or using your phone with your thumb.

Scoop your baby up with your palms facing up and your hands under the baby, rather than lifting under the arms with your thumbs. Keep your wrists straight.

Use pillows during feeds so the baby's weight rests on the pillow, not your wrist. Change sides and positions regularly.

Share lifting and carrying with family members where you can, especially in the first weeks of pain.

A thumb splint (thumb spica) worn at night and during heavy tasks rests the tendons. A cold pack wrapped in a cloth for 10 to 15 minutes can ease pain after a busy day.

Reduce repeated thumb movements such as long phone use and wringing clothes by hand.

Once the pain starts to settle, gentle thumb and wrist movement, and later strengthening, help the tendons tolerate daily load again.

If the pain is not improving after a few weeks of changes, or it stops you caring for your baby, see your doctor. A steroid injection is an option that helps many people. Discuss it with your doctor if you are breastfeeding.

Numbness or tingling in the thumb, index and middle fingers suggests carpal tunnel syndrome, which is also common after pregnancy. A hot, red, swollen wrist or fever needs a doctor promptly.
