I've always had a high tolerance for pain.
I've shut my fingers in a car door, had a hatch back hit me in the head, bashed my knee against a boulder while snowboarding, rolled my ankle several times skateboarding, had several groin shots, had glass in my feet once, been hit with several guitar and bass headstocks, I've had numerous scrapes and bruises, several black eyes, and have cut myself with my grandpa's knife to the bone once.
From judo and boxing, I've gotten several bloody noses, been choked, and have been slammed so hard I got whiplash on the first day of judo. It hurt, but I lived.
Never have broken a bone before, though.
But by far the worst pain I've ever had was when I still had my gall bladder. Apparently, according to the doctor, it was as hard as a table, because it was full of gallstones. Don't ask me how, my diet isn't that unhealthy.
When I still had it, I would get insane stomach pains that would cause me to double over, and twice the pain was so unbearable I threw up from it.
Got it removed, and hadn't had an issue since.
In regards to painkillers, because of the opioid crisis in America, doctors only prescribe the bare minimum, which is sensible, but even then, I hate painkillers. They make me too loopy and I don't feel in control, so I try to get off them as soon as I can bear the pain.
To me, pain is only temporary, and if I can fight through it, it's not so bad.
