Mom's advice please. I have severe back pain. It is so bad I had to call in to work tonight . My pain level is at 10. I am not far along in this pregnancy and hopefully find out tomorrow how far. I had back pain prior to my last pregnancy and thru the whole pregnancy. But never this bad. Little cramping in my belly. Left side feels like it's full of air, which causes more pain. And a pinching pain in my back as well. What could this be? I Google and scared the shit out of myself. I would rather hear your opinion. And what can I do to ease it right now til I get to the OB in the morning.
