Fredrick,
Xifaxin mostly stays in the gut and is not systemically absorbed, so when your Doctor said it kills skin bacteria too, I must ask if you checked to make sure he has a medical license because he ought to know what he is prescribing:
https://en.m.wikipedia.org/wiki/Rifaximin
“Because Rifaximin is absorbed poorly, most of the drug taken orally stays in the gastrointestinal tract where the infection takes place.“ (see above link)
Go to a dermatologist and have a scrape taken of your skin and if it’s positive for a fungal infection you may be given diflucan. As I noted above my fungal infection was severe and all over my legpits and groin. It was spreading and out of control and I was given diflucan and diflucan kaboshed it big time in two weeks. It’s also amazing to watch a massive fungal infection on your body die. It was like rubbing death off my skin every day. Sort of like peeling skin but more of a powder-like peeling sensation of death. I felt like I was washing death off my legs and groin for weeks.
You asked what my biggest issue is with the J Pouch. I don’t have any big or biggest issue. I did have my annual scope today and my doc said it looked better than last year. I have a bit of inflammation at the J Pouch inlet (which I always have) but otherwise everything looks good. So I don’t have any issues at the moment.
