I was hit by a 12lb shot in 9th grade. Stupid coach had told us to go mark our throws so we could measure later as he took the tape measure to the discus field. I threw, walked out to mark my throw, but kept an eye on the guys horsing around behind the circle. I faced the circle - nobody was in it. I bent down quickly to grab a stick to jab in the ground and I hear, "heads up!"
The shot missed my head, thank God. Could've killed me. It hit me in the back. I was in a bit of shock. I slowly stood up and saw all the guys running toward me. They were all yelling and asking if I was ok. I didn't say a thing. I just turned and started walking the couple hundred yards to the trainer's room. That guy told me it was probably a deep bruise. Ha.
I went home and ended up coming back to school that night to show my science fair project (3rd place, holla). Went to the doctor the next day.
The lower, narrow end of my left shoulder blade was broken clean off. Luckily, it's between 2 muscles and didn't move. It healed on its own. Sleeping, moving, breathing, coughing, laughing all sucked. Similar to broken ribs.
The school called my dad asking why I wasn't at school and then threatened something about holding the absence against me. My dad explained in a calm manner (not so much) that their incompetence had led to my injury, and they're lucky I wasn't dead or brain damaged.
