Hi. I got what looked like a pimple at first, but eventually grew a lot bigger than what I consider a pimple would and I have NO idea what it could be. It popped and a lot of puss came out, but the bad part about it, it's that now I have a huge hole where it was. It didn't and doesn't itch or hurt, except that not it stings a little bit, but nothing big. Does anyone have any idea what it could be and what can I do? Thanks beforehand.
