Me too, Julia.
I'm always thinking we can do heart transplants, brain surgery, and there is this tiny pocket of infection that I can tell them exactly where it hurts and they still can't find it... :)
The flagyl and cipro make me feel constantly nauseated. I've lost 5 lbs in 4 weeks, just from lack of appetite. I think the flagyl also gives me heartburn if I don't eat just right. I was having a lot of D right before they put me on them, I think from the inflammation in my rectum, but that IS actually better on these drugs.
It also helps me to feel like I'm not the only one in the world dealing with this- it's not exactly polite coffee talk! I heard somewhere- (maybe on this board!) that up to 50% of people deal with a rectal abscess at some point in their life, but no one talks about it.
Incidentally, my abscess showed up on a rectal ultrasound vaguely- they initally called it a "fluid filled cavity" but NOT on the MRI I had a week after... strange, huh?
I'll keep you posted.
