Sorry to hear you are having issues @acres When I had taken to much antibiotics I also had C-Diff. I had a colonoscopy after as well to make sure it wasnt stuck in any places. When I say getting stuck , I had ulcers when I was younger and beyond the c-diff bacteria can stay in those spots or any area. I would suggest to do it., there maybe more there or your body just is over load with antibiotics now and they are not working. Transplant is a great option. I was having issue with my gallbladder and it was removed before I had c-diff. I have issues with bm because of my chronic pancreatitis, I check my bm always and forever. I also have IBS, but that was checked after c-diff. Which I have been a vegan, vegetarian and gluten free. Nothing really worked for me or help my IBS issues. I am glad I went to the Mayo clinic, which they found everything and I had seen many Dr. By then as well. I hope your doctor's are talking to each other or you are going in circles. I just had my 10th colonoscopy since I was 32. Write everything down the doctor says and ask questions. Good luck and keep us updated.
