re: What’s the worst injury you’ve ever had?

Racing motocross back in the day. Hit a big jump wrong and went over the bars. Landed around 70ft from the face of the jump on my head and shoulder with the bike on top of me.
Concussion, broken collar bone, dislocated shoulder, torn labrum, broken ribs, collapsed lung, 2nd degree burns on my back. Spent the next 3 days in the hospital.

Had another incident wakeboarding where I landed a little twisted and off axis. I immediately felt my knee pop and what I can only describe as feeling like an electrical shock blowing out the bottom of my heel. Hurt like hell, I immediately knew something was wrong and dropped the handle and kicked the board off as fast as I could before the pain set in. It took 2 days to get into the Dr and my knee was swollen pretty bad.
Turned out to be a contusion to the joint, bruised femur, and a functional tear to the ACL. I got lucky, just a touch more and my knee would have been trashed. No surgery needed, just some rehab and I was good to go.
That pretty well killed wakeboarding for me, I didn't get on a board again for a year and never tried another trick.
