Serious Pimple Issue?

I think you should ask a doctor about this problem. Or maybe wear tank tops so that way it could air out your armpit or else you can shave your armpit a little bit so the hair won't be in the way. You should also stop eating fried food because fried food isn't healthy for you and it will cause you more pimples. Another method is put fresh mashed potato on it, it helps with black heads but not sure about that big pimple. Or you can use lemon juice but it will stink a lot! Good luck :o
