I never really had excruciating pain, but here's some minor ones ...
Broken wrist, 6 years old, fell off monkey bars.
Broken wrist, 18 years old, rollerblading. That didn't hurt much. Until I tried to move it.
Got my hand slammed in the door of a 75 Camaro.
Splinter, at least 1/8" thick, almost through my hand.
Cut the corner of my finger off with an X-acto knife.
Getting 2 needles of novacaine or whatever they use into said finger. OUCH.
