Thank you Dr. Hasan for your reply.
As I mentioned in my earlier post, I did have a stool culture done about 6 months ago to check for c-diff and it was nagative. But I have been feeling worse the last couple weeks. Is this common with IBS, for it to change or be worse at times? Also, me being on the low dose keflex for three years now, do you in your professional opinion believe that since I have been on the low dose keflex for so long, would I have already gotten c-diff a long time ago if I was going to get it from taking the low dose keflex? I was told that keflex is not a huge cause in c-diff like the second and third generations, is this true?? Also I mentioned I do take probitoics daily, is this suppose to help prevent c-diff??
