Hi and welcome.
I've never had a c-diff infection, but I know others on here have. Maybe they'll be able to provide some insight. I do think that if you're not improving much after two weeks on the new antibiotic, you should contact your doctor.
Are you on any medications for your UC?
Also, if you are using your real name as your screen name, you might want to change it. It's a pretty unusual name, and you never know if there's a crackpot on here who might decide to figure out where you live or something. And, if you are ever looking for a job, and your potential employer does a google search, they would figure out that you have UC. Employers aren't supposed to discriminate about
stuff like that, but you know they would.
