I have a BCIR but a pouch is a pouch. I have this pain a lot. I feel like shards of glass are stabbing inside my pouch and all up my lungs and rib cage. I always sound crazy when I explain it. When I go back on Omniceff (stronger antibiotic than Cipro) it kills it so I think it is part of the Bacteria Overgrowth infection I keep reoccurring. Might be pouchitis as well. We are all different though and I am no doctor just sharing my pain.
