Arm broken isn't that Bad tbh, when it happens you get a lot of adrenalin so the initial break isn't that Bad. And then if you're just sitting around with it broken it doesn't really hurt unless you move it.
Source: broke forearm and had to wait a week after to get surgery to put plates in. So I kinda just walked around with a bent arm in a sling for a week
Broken arm, collar bone, and pinkie toe all barely hurt 99.9% of the time imo (they'd only experience discomfort if they were stressed) - I'd rate them all 0-2 and two were bad enough to need surgery. But like, also my conscious sense of pain has gotten worse over time. I don't know what it would take for me to rate something above a 5 anymore.
I broke 3 of my metatarsals in my right foot all at the same time and it didn't hurt at all until I got surgery. I could press on them and feel the bones moving, no pain. After surgery, the most pain I've ever been in.
I have no idea where to rate pain at the doctor at all because I don't know if they're supposed to hurt or not!
