A few years ago I was playing basketball and the ball jammed my pinky. I looked down and it was dislocated. Before the pain hit I pulled it back into place.
When my daughter was 2 she pinched her finger at a museum and split the nail horizontally. If you opened it you could see down to the bone. I did what any responsible parent would do. I wrote her a script for antibiotics and put triple antibiotic ointment on it, with a bandaid change twice a day.
I woke up in the middle of the night with the worst headache of my life (if you are not sure why this is a bad thing, google subarachnoid hemorrhage). I started puking and was terrified I had a SAH. My wife called out from the bedroom asking me if I was okay. I told her I was fine and she should go back to sleep. Once the vomiting stopped, I did what any responsible ER doctor would do, I took 800mg Motrin (if I had a head bleed I was going to make sure that my chances of survival were 0) and went back to bed, terrified that my wife wouldn't be able to wake me up in the morning.
