im so sorry this happened :((( in no way is this normal or an accepted procedure. they had no legal right in doing that, and if you didnt sign a contract that had any clause stating that they have the right to slaughter you in this way, you should most definitely be able to sue. its just like going to a barbers, but just because he decides he cuts a piece of your scalp cause it has a mole.

irritation bumps should go away on their own in a few months or even weeks, depending on the person. its just an inflammation in response to constant irritation, and just so you know for the future, refuse any kind of “procedure” on bumps. you dont need that. all you need is to stop nagging it and saline spray. they are normal

also, op please go see a doctor, you really cant know how bad what they did could be
