A pain I recall vividly--or least I recall it was vivid at the time--was the three or four weeks after a total hip replacement. It just plain hurt, but since I wanted to get back to wing chun practice I did my best to pretend it wasn't there. Funny, but looking back on it now what I remember most was the needle shots to the stomach area (warfarin?) to prevent clotting and possible dvt. In hospital I took pain killers to get to sleep but tried to avoid them during the day and the nurse checked with the doc who must have said it was ok. What got me up and moving was a nurse telling me post-op that if I didn't urinate before noon they would have to catratize/catheratize/catherize stick a tube up my pecker. That got me out of bed and struggling to get to the bathroom right fast lemme tell you.
