Is an injection in the nose a chest injection?

It's been about 2 months since my surgery~ I'm having a re-surgery~ I used to have a good-looking Bokko nose ~~~ Because of the old surgery, I had a lot of scars on my nose. Yeyoung Still, it's a lot better than it used to be, so I'm living my life satisfied~ This time, as I approached two months at a hospital, they told me to come and give me an injection into my nose.. If this is right, it will make me look worse... Is this an injection for the chest??? I'm worried that there is a risk of necrosis if it hits me, but ,,, I've suffered a lot because of my chest pain so I want to get hit ㅠ ㅠㅠㅠ If I get hit with this once, it will work right away?? I have a lot of questions... How many times do I have to get it right? After all, after being hit by this, you don't have a chest, right? Ah,,,,,, a nose that has a lot of fat naturally produces a lot of sebum, and,,,, originally, it is said that Bokko is the same , but I have two cases . ㅠㅠ Please give me some answers to the holy grail masters ㅠㅠ
