These are pretty common locations for pouchitis. I still think you have two things going on. The obstruction symptoms and enlargement upstream from the stoma site aren’t likely to be related to the pouchitis, IMO, but I think that’s causing most of your discomfort. That will probably clear up on its own, as most partial obstructions do. They may be using the word “obstruction” in its medical emergency sense (i.e. a complete obstruction requiring surgery, which you don’t have) rather than the looser way we often use it on this site. You haven’t described any classic pouchitis symptoms, but it’s probably worth trying to get that pouch inflammation under control, as they are doing with the antibiotics. Are they giving you the antibiotics by mouth? Are you eating anything? If nothing much is moving through then eventually that stuff has to go somewhere.
