What antibiotic does your Dr. put you on when you have a diverticulitis infection? The first 4 attacks I had went undiagnosed because they happen with the onset of my period, so my Dr. believed the pain to be endometriosis. Even the emergency room doc believed it to be endo. Finally went to a gastro Dr. who did a sigmoidoscopy and took a biopsy, sent it in, and confirmed it was diverticulitis. So the fifth time I had an attack, he called in Augmentin for me. Made the diverticulitis better in about a day and a half (the other four attacks lasted for about a week and a half). But two days into the Augmentin I got such bad diarrhea and cramping, I thought I was gonna die. I'm not sure which was worse. After that my IBS was really bad for a few months. Finally took probiotics and I believe that helped restore my intenstinal balance. But I was wondering what antibiotic you are prescribed, and if it is as harsh as Augmentin? If I would have taken Culterelle with it, would I not have gotten the bad diarrhea and cramping? I am dreading the next diverticulitis attack because of how the antibiotics messed up my system.And now my gastro doc is wanting me to come in and talk about a colon resection. He says I have had way too many attacks, and I need to do something about it.
