Anyone heard of Post Infectious symptoms that mimic IBS?I was diagnosed with IBS a year ago after recovering from a Pneumonia (5 weeks on antibiotics). I underwent a full Colonoscopy, Gastro and Ultrasound. No organic problems were found. I experience primarily IBS-C symptoms and with propper diet IBS-D was occasionalRecently I went to a new doctor, who suspected it was a bad bacterial overgrowth. I took ANTOX (ciprofloxacin) for 5 days. After that the C and D symptoms had disappeared, but the abdominal pain is worst.My question is, has anyone experienced or heard a case like this were IBS was caused by bacteria and if so, is it normal that the pain remains still after antibiotic treatment?My doctor says it is a Post Infectious symptom and that the pain should eventually go away, but regarding IBS I got used to trust doctors only 50% (not that I intend to know better than them).Any ideas, comments or anything will help me a lot, even if they only serve as comfort. Thanks in advance.
