Interesting post. I could sleep on any side or my back for about five years post takedown. Then I had a horrible case of cuffitis along with something my doc had never seen before. He called it a fizzure for lack of a name for it. I was in a lot of pain and suddenly had to go every time I slept on my right side. This has slowly, as in over four years, gotten better, but to this day, I can only sleep on my right side if I have just emptied my pouch.
I never thought this was a pouch thing. Now I know it can be!
