That sucks. I may have ruptured my appendix, but then again, I'm no doctor. All that I know is that it hurts like crazy (I'm not exaggerating, I've had my leg ripped open with little beads of fat coming out before), I can't really stand up or walk, it only hurts from about the top of my hip bone up to about six inches under my armpit, and it goes a little bit into my stomach. Also I can't really eat without feeling like it's just going to come back up. Oh, and I know of a guy who ruptured his appendix and had to be flown about four hours away to a hospital.
Hopefully it gets better for you.
