question: Hello doctor,I am suffering from abdominal pain and diarrhea three to four times a day for the last four months. I have gone through colonoscopy and sigmoidoscopy followed by a biopsy. As per the biopsy, it is a mild non-specific inflammation. So, my doctor did several tests like fecal calprotectin, and ASCA-IGg to check for IBD. However, the results were negative. I have got a stool occult test done, and it came back negative as well. At present, I am taking Rifaximin 400 mg, Librax, and VSL#3, but the problem is not solved.
