Roller hockey, of all things - against another school. So no shoulder pads or hockey pants. Got cross-checked in my left hip area while coming around with the puck. It felt a bit weird the rest of the game, not real pain but a bothersome nagging pain that wouldn't let me stand up straight. It was a doubleheader but I couldn't stay for game 2 due to the "pain". While driving myself back to the dorm I started getting the sweats real bad. As I was nearing the final turn home I felt myself starting to black out. I completed the turn.
Then I felt myself peeing my pants - I realize I'm in the middle of the road and I've been blacked out, yet was able to put the car in park beforehand. Pissing myself was some kind of miracle response by my body at that point.
I got back to my room and tried to sleep it off. Since I couldn't, I called the school nurse, who basically saved my life. She said anything having to do with the abdomen I must go get it checked out. A friend drove me to the hospital where I blacked out again as soon as I walked in. I woke on the trauma table shivering uncontrollably. Man that catheter hurt so bad. A scan showed I had ruptured my spleen and it's bleeding internally. They said surgery was necessary and I remember worrying about not waking up from it at all. They had me count backwards from 10 and I was out like a light at maybe 8.
I supposedly woke up after surgery thrashing around so they had to put on restraints, which was the first thing I remember after waking consciously. Some people don't take sedation well. Abdominal surgery is no joke - every time you move you need your stomach muscles. It hurt like hell moving even the slightest. The staples, 6-inch vertically down my stomach didn't look all that great either. I also had intense stomach pains that felt like gas that could not escape throughout the next few days. I also fainted once while in the bathroom and they rushed people in to help me again.
After being discharged, I spent the next 3 weeks sleeping in my gf's dorm room while she cared for me. Meanwhile my teammate wrote a scathing letter to the other team's captain about the crosscheck - it wasn't very well received.
This scar remains pretty prominent some 16 years later... the doc lied about it fading. It was a freak accident and I went back to play a few months later. If I were smart, I would've just started with ice a long time ago and none of that would've happened - I love it so much more now.
