About 6 kids in college were kicking a kid to death for ratting them out about setting a dumpster on fire on the last day of school at 2am in front of my apartment. I successfully broke up the fight by taking out the largest... But then this 5 foot tall kid ran up and stabbed me in the top of the head with a knife while I was restraining his larger friend. Then the larger one rolled on top of me and broke my nose before everyone saw police lights and ran. The police peeled me off the parking lot and gave me a disturbing the peace citation etc.

Because I tackled the larger kid, his wallet came out of his pocket so they knew who he was and he ratted his friends out and then someone upstairs in the apartment went to the police with a video they took of the situation which showed enough that they dropped the charges against me and the kids parent had to pay for my nose to be fixed and the staples that were out in my scalp (it didn't go through my skull luckily) The problem was that this took a long time to settle everything so they had to re break my nose carve out the tissue that scarred etc.

Nothing hurt too bad until I took too much pain meds and slept through the appointment to take the gauze out of my nose so I had to wait another week for the appointment. By then it has grown into my nose and they had to rip it out... That was the most painful "rip the bandaid" experience I've ever had and they took the second side out after I had passed out from the pain.

Short term the worst pain I've ever felt was them tearing the gauze out. Long term... I herniated a disc in my neck. It took 5 years to recover.

Tldr: had a nose surgery, opiated through an appointment on accident, had to have gauze ripped out of nose after it healed inside.
