I wonder if that doctor has ever had major surgery himself and been told not to use painkillers? Even if that is the case, pain seems to vary greatly in how it affects people. I would be very hesitant to tell someone that they should just let the pain "guide" them, because I have no idea what it is like for them.
I agree that there is no "one-size-fits-all" medical solution, but perhaps having this base-line allows building up when discussed with one's doctor - the article does not discuss this post-operation re-negotiation of how to manage the pain. Perhaps some HNers have experience with a similar situation that they could share.
The guy who operated on my penis gave me a grab bag of pills that went right up to serious prescription pain killers and said just to call by if I needed more. I never even took the first day's pills, it barely hurt at all, but then he's a penis surgeon, it's not even essential to _have_ a penis, half the population don't have one so how important can that surgery be?
The guy who used to be my dentist before he retired was a Max Fac surgeon in his day job, dentist was how he relaxed before the weekend. So, normally he's putting back together ruined faces from car accidents and that sort of thing. Need a filling? "I can numb that, but it's in your lower jaw, and it's not touching the root, so I suggest we go without, then you won't drool for the rest of the day". "OK, but it will hurt?" "Barely at all, slight discomfort, weird sensation, no real pain". He was right, it was fine, definitely worth the small amount of discomfort to be in and out quickly and not drooling like an idiot.
On the other hand, when I was a kid I got hit by a car (my fault), they used Entonox (medical laughing gas) back then, I was high as a kite, and given the car smashed me good, that was probably the right call. So I'm not saying "I never use pain killers" but more like "I think pain killers are something to reserve for when it's really bad, not the first thing to reach for every time".
