My hands and fingers do and seize up into a claw but it's a neurological thing apparently so docs tell me no relation to pregnancy :)
Yes! So weird. My left arm went very weak and sore for a few hours. Called my doc- they said it could be a nerve thing. If your hands are numb it could be carpel tunnel- much more common in pregnancy. You can get braces to help with it!!
Yes this morning my whole right arm was tingling and numb for Like 20 mins, weird but it went away :)
