I had my tonsils removed when I was two.
Tubes in my ears 3 times as a kid.
Two eye surgeries, the second one, a follow up to remove a bump from the first surgery where they had to cut the front of my eye off and 'rewire' the muscles, I stayed awake for, they just put numbing dops in my eye. So I was awake with medical paper/tape over my right eye, and could see the scalpal coming in and out and all that.
isdom teeth removed.
Front teeth knocked out from a bar fight. Had those surgically implanted with metal rods.
Some teeth crowned, root canals for all those.
Severe laceration on my left forearm that required like 3 hours of surgery, 40 stitches and 15 staples.
Even more severe laceration on my right arm that required 8 hours of surgery and 100 stitches and 35 staples.
I bleed to death on both of those and came bck. The second one, I they used 17 units of blood, and the human body only holds like 12 or so. So I was bleedin hard on that one.
Severed tendons, muscles, arteries, main nerve, everything got sliced in two, all the way to the bone, and all the pressure from that caused my elbow to break, so I had to wear a robocop arm brace for 6 months.
That's all I can think of. I'll post pictures of the laceration scars later. They're pretty nasty.
