Hi, Yes I've had this experience. Usually along with the air escaping there is some discharge of the contents of the pouch. I can feel it sometimes but not always. I believe the air is gas. Sometimes the gas build up is a lot and there is pressure in the pouch and I HAVE to empty the pouch to relieve the discomfort. But I feel that the gas and discharge are normal. When this occurs, I don't believe that anyone around me knows what is happening but me. We all pass gas whether we are aware of it or not and we all do it whether we have a pouch or not. So I'm sure this is a normal process. But our bodies change over the years. For me if I'm able to empty the pouch with little to no difficulty I'm happy. If the scope came back normal and your doctor isn't concerned, I wouldn't worry about it. I think with all the current events happening stress is up and stress can affect us even if we are not aware of it. So I'm trying to stay positive and calm. I hope you are able to do so too. I hope I've been able to ease your mind a little. Stay safe and well.
