I will say in advance of telling the story that if this is a contest, I win.
2nd hole of a tournament round at a HS coaches convention at Jekyll Island I was hit in head/ear by a ball off a 3 wood from about 30 yds. away. Flush; ball ricocheted 30 yds. back into the fairway. (I won't even try to explain how this happened.)
I went face down in the floor of the golf cart in a puddle of blood; the top part of my right ear had been torn off. (Think Holyfield's ear after Tyson bit him as a visual.) Never lost consciousness, but it took a few minutes to get vertical again. All four of us were certified in first aid/head injuries/CPR, etc; knew I wasn't going to die (or get better right away, either) so...
I held a wet towel to my head until it was my turn to hit, and played the remainder of the round. It never did stop bleeding, but I was wearing a black shirt and a black hat, and I didn't really have a sense of how bad this really was until we finished and I saw myself in a mirror; dried, crusted blood everywhere. During the round, I was so dizzy that I couldn't hit the ball especially well, but the weird thing was that I have NEVER putted as well before or since; I made EVERYTHING! My friend who hit me, btw, was just ruined; he thought he had killed me, and he couldn't play at all for the rest of the day.
After the round, we went to the ER in Brunswick, where, as it turns out, golf injuries are a fairly low priority on a Friday night. When I finally got looked at, the ER doc tells me that I'll have to have plastic surgery with a skin graft from my hip because the piece of my ear was gone. He wraps me in a turban/pressure wrap and sends me on my way. I play the rest of the weekend with the bloody turban, and become sort of a legend in certain circles of Georgia high school coaches. This was almost 25 years ago, and I still see people who ask me about it, or kid me about it.
Two final pieces of the story:
First, if you ever have the need for a plastic surgery appt, do NOT call your wife from a buddies golf trip and ask her to make the appt; that call did NOT go well.
And second, when I finally got to the plastic surgeon, I told him that the ER doc had said I'd need a skin graft off my hip; he studied me carefully, and said, "Nah; that ear was too big anyway!" I told him that there were a lot of other ways he could have chosen to say that...
