Julie - some of us will have opinions as to what might help you...however...it is the suregon who put the pouch together who should be listening and working to resolve your discomfort.
Keep working to get this doctor of yours to resolve this concern. I think it has gone on too long. I know many of these surgeons have hectic schedules but he did do the work and should want to make things right. At the three month mark, life with your new bladder should be more predictable, but in a good way. Stay after this guy until you get some relief. You are the customer and your insurance has paid a good dollar amount, I am sure. None of us likes to be a pain in the butt, however, sometimes it is necessary to get the attention of the right medical folks so they will listen to us and respond appropriately. Get the mindset of a pittbull and don't turn loose until you get what you need !!!
