So glad things seem better. You know, regarding the pack putting pressure, I think that could be accurate. Now I am thinking I am doing something I probably shouldn't be . . .
I have been using bandages now around my abdomen when I go swimming. The other wraps I had been wearing weren't concealing things to my liking, so that's why I started with these. They conceal really well, but I have been worrying about too much pressure being applied to the area. I still get output while it's around me, but sometimes I have A LOT of output in my bag after I take it off. I wonder if it keeps things sort of trapped in there, and the plumbing isn't able to work as properly. I don't know, but this could be similar to what you had happen, and since your foods are more thickening it was more severe in your case?
I was thinking of just going back to the wraps and just dealing with the buldge. Seems safer in the long run. Hope your situation was as simple and there are no other issues.
