Do any mummies feel sudden pain in the chest?

Oh yes, I've had this before too! That sudden sharp zap in the chest that comes and goes in seconds, very unsettling feeling! It could be so many things like stress, posture, or just tiredness from carrying the kids around all day. But since it's making you uncomfortable, I'd really encourage you to see a doctor soon, just to rule out anything, especially if it keeps happening or comes with breathlessness or dizziness lah. Better to get it checked and have peace of mind than to worry at home!
