Why not? Rank 1 pain is just boring. 2 and 3 is where it gets more fun! /hj
Temporary pain can be fun (like leg cramps <3), but if it's uncontrolled and continues for a long time it can be annoying. Definitely agree that the smiley choices on that sign seem a wee bit too masochistic to be making these signs for general use...
Feels right to whom? A 1, maybe 2, is probably how I'd rate it if I was trying to be honest unless they're seriously stressing it without a warning. In which point, I'd just be totally confused how to rate it, but they could probably get a decent idea about the discomfort from my reaction.
Or feels right for the injury I assume I have? Should I just guess what other people would say or lookup values on the way to the ER?
Or go somewhere in the middle so it's not so obvious I'm lying about experiencing pain when I look like I'm not really in pain?
