Wow, sorry to hear the transplants didn't work, they sounded so promising.

I never found probiotics much help either.

Other thoughts... SIBO? (Google that one)

Oh... just read about a sort of tick on the E. coast that can cause intolerances to meat. I posted about it here within the last year (media section). I know you live in a rural area.

Diarrhea could be one of the symptoms. Do you get that sort of reaction to non-red meat?

And I'd get an endoscopy done at the same time as the colonoscopy just in case it is in the small bowl.
