Pregnancy carpal tunnel is actually caused by fluid retention pressing on the nerves. Wearing a wrist brace at night helps keep the wrist straight and relieves the pressure. Still, it's best to consult your gynac to ensure it's normal swelling and get their professional advice.
If your doctor has allowed it, some gentle wrist rotations and basic prenatal stretches can improve blood flow. I used to do very light hand yoga stretches which really helped ease the stiffness. But always ask your gynac before trying any new exercise.
My hands were so swollen with twins that I couldn't even hold a glass properly, felt like a robot! Wearing wrist splints at night really saved me. Also, try doing some gentle finger stretches and avoid holding your phone for too long.
I tracked this symptom on my pregnancy app and it suggested avoiding repetitive wrist motions like typing. It also recommended using a warm or cold compress on the wrists. Elevating your hands on a cushion while resting also makes a big difference!
