Oh my yes, this is exactly what's going on and you can add nauseau, dry heaves, serious burping and gas, can't eat. That's what got me admitted. I felt like I had a bad flu. Going on for 4 days. Being treated as pouchitis. My doctor gave the team a long list of tests, oh fun, not sure yet about the plan. The Iv fluid got my pouch to open up, it was barely working, I hoped I would feel better but still feeling sick this am. This happened 5 years ago As well.
Your are the first for me to hear that you experienced something similar. Other pouchitis posts don't mention these things.
