I read a lot of the Q&As on here about pimples on the nipples and got most of the answers I was looking for. However, I have a really deep and apparently connected pimple on my breast because when I squeezed one side of my nipple (I've learned that this is a bad idea) pus comes out a pore on the other side. I never thought a pimple could be so deep! What is this and how can I treat it if i can't get any medication in it?
