You've done well to go all this time without needing any form of surgery! With pain, and recovery, that is a tricky one, as we are all different. I can tell you that for me, it wasn't too bad at all. Some discomfort in hospital, but I beat the hell out of the PCA anyway, because.. hellooooo.. happy juice!! Same at home, minus the PCA. I always bounce back pretty well after surgery though.
I could still get get up and do what I needed to do, but I did get tired pretty easily. Maybe you could prepare some meals before you go in and freeze them? I made a buttload of stuff that could be defrosted overnight, then just thrown in the slow cooker the next morning.
