Replying to Injuries you dont remeber getting

Just wondering what the worst injury you've ever gotten that you dont remember getting was. Mine happened a few days ago treeskiing in steamboat springs. Apparently I got rocked by a tree and I dont remember shit. I woke up in an amberlamps with a fucked up arm and hella whiplash. I was like 93% sober so I dont think that was why I cant remember anything, and im not concussed. The doctors told me my brain was fine but my neck was all screwed up. So tell me about your worst hazy injury experience so I can judge you!
