I had the same symptoms as you a few weeks after my takedown (Nov 2018). I had so much pain and gas. Finally my GI gave me Cipro and within 24 hours I felt so much better. I continued on that for 2 weeks and after taking me off all the symptoms came back. To make a long story short, I was on and off Cipro until they decided I have chronic pouchitis and now I don't go off antibiotics. I take Cipro (500mg) in the morning and Flagyl (500mg) in the evening. With these meds, I finally feel normal. I've tried to reduce the amount I take and within a few days my symptoms return. So I've come to terms with always being on meds but it's so worth it. I hope you find relief soon.
