I sometimes have the same problem. It actually has to do with your spine not being centered correctly. I see a chiropractor 2xs a wk. If you can you should too. I seem to have a pretty big baby in there and I'm big for 5 mos. It really helps to get chiropractic care and it's safe while pregnant. I hope you feel better soon....

I'm not really sure, I've never had indigestion or heartburn. It literally feels like someone is trying to pull my ribs apart. Sometimes it almost starts tingling and going numb because of this pain. Obviously I can deal with it, I just didn't know what it was.
Is it possible that you are experiencing indigestion and it is just a coincidence that you are standing a lot? Heartburn and indigestion can give some pretty uncomfortable symptoms if they get bad. I once felt like and elephant was sitting on my chest and I felt like I couldn't breath in, all it was was indigestion.
I would mention it at your next appointment and see what your OB says.
