A low pain threshold saves you a lot of pain. I have the opposite problem, and am also very refractory to anesthetics.
I had only two surgeries, one for a badly broken thumb, needing screws and surgery, and one for tonsils at age 38.
First time, I told them all they were doing, until they injected something in my IV and I just passed away.
Second time, after pumping the standard dose into me, I was awake like before. So they just “killed me” again by IV.
Dentist is a torture...
I wish I had a lower pain threshold...
