Hi jobear, I know what you mean, It's really scary. I get pains too in my chest and shoulders, sometimes the pain is different day to day. I do get acid reflux, I think it has something to do with that. Try and stay calm, maybe you should get someone to give you a hand with the baby if yiur not feeling to good. You should see your doctor though to put your mind at ease. Im sure your fine. take care
