So blockage is a possibility - your outward symptoms make it sound more like that, or gas. You didn't say anything about your outpout or lack of it. That is important when assessing blockages - or partial blockages. Usually you will have the following with a partial blockage:
- Abdominal pain at the site of the blockage
- Output, but less than usual
- Possibly diarrhea or loose stool
- More burping than usual
With a complete blockage - take those symptoms and amplify them (abdominal pain - but horrible pain that increases in intensity and frequency, No output at all, etc.).
Could also be pouchitis - though I typically don't have abdominal pain with it when I get it.
