Combining ibuprofen and naproxen can get you into plenty of trouble even without a J-pouch. Your pouch may heal up fine now that you've stopped them, and hopefully you're getting your anemia under control. Dilation of your stenosis with a finger is a common technique, and generally pretty safe. Have you tried it yet? If it creates intolerable pain you may need to let the doctor do it, but that's much less convenient.
