Fingers swelling up

Same here, yup it's water retention with carpal tunnel syndrome. Painful to make a fist due to my fingers swelling. my hand numbness tends to occur more when I bend my wrist towards myself (for example holding my phone while in bed), so I'm trying to be more disciplined and avoid those wrist positions. can try shaking your hands/wrist during numbing episodes; you should feel relief quickly if it's due to carpal tunnel syndrome :).
