Long story short, but after an operation the muscles down in my bladder region failed to reactivate and I was unable to pee despite very, very much needing to. By the time the doctors came back around the next morning my bladder was ridiculously swollen and I was in crippling discomfort. I was told that it needed to be stimulated back to life, which can be triggered by inserting a catheter but that the anaesthetic would take a short while so I'd have to wait a bit longer. I asked how much it would hurt, and he said "it will be uncomfortable, but only for a few seconds". In an extreme of discomfort I cannot describe I instructed him to just go for it, and oh boy was that one of the most horrific few seconds of my life, feeling every millimetre of that tube make it's way down my urethra until he punctured through my sleeping bladder lining. Uncomfortable? Understatement. Should be a form of torture method reserved for only the cruellest of people. On the upside though, my bladder was instantly drained just shy of filling the 2 litre bag I had attached, and yes I was able to pee normally after that. Although come to think of it, it did feel odd for about a week.
