I got a concussion once when I was doing laundry in college. They were stacked dryers and the top door was open and it was eye level so I didnt see it so I bent over to get my laundry in the bottom one and smash I hit the dryer door and got concussed for about a year from it. It hurt like hell.
Not very embarrassing, but I sprained my ankle playing basketball, and then I subsequently broke my arm playing soccer. Kinda funny how I broke the "other" limb when playing a sport
I think the worst pain I've ever gotten was when I was working in an exotic pet store and no-one told me it was the day they feed the pythons (it was my first day). So I go into the reticulated python tank (they were about 20ft long and HEAVY), go to pick up the waterbowl to refill it and one of them tagged my hands before I even had a chance to react. He got both my hands down to the bone, and it took 3 people to prise his jaw off me. The snake was coated in my blood.
oh man. One time I was cutting palm tree branches on a ladder and one fell on top of me. The spiky parts sliced into my hand and I still have a nice big scar to this day for it
