Need a doctors help

Ellie • The world is a weird and wonderful place!

I told my dermatologist that I had popped that pimple when it was white and he put me on antibiotics. Because there is a risk of brain infection with these pimples. I popped it yesterday and it seems healed already. I am breastfeeding so antibiotics for something like this seems crazy. Anybody here that can give me a second opinion. I popped it with clean hands and then put alcohol in the pimple.
