Nice scale, I think it's the one I found once and was looking for it afterwards. Because, well, there isn't any universal pain scale, for example once I found one that insisted that level 10 means you passed out.
If you're not into words, Hyperbole and a half has a nice
picture-esq pain scale too...
Anyway on the OP scale, I think I'm usually around level 6 - definitely don't want to do anything to not trigger something worse. It messes with my head too. Although I'm so used to it by now I don't really think about it, but it definitely prevents me from doing much of anything. It's only when I stuff myself up with painkillers I realize what a strange feeling it is to not actually have pain.
It's gonna be bad when I run out of pills in a few days.
