I'm kinda similar to Tracy916- when I get the nasty, pains in my back and I know it's not from my exercise regimen, I know it's probably due to bloating. Usually anti-gas Maalox, Pepto or something similar will take care of it, but sometimes it's bad enough that I just have to ride it out.

I don't recall having any other types of back pains during my first few weeks- sad as that is since I only started 7 mos. ago.

Best of luck!
