Hey laura~ I'm seeing this late, but glad that you went to the Dr. My DS has had a couple of cysts that sound like yours. One started out hard and small and then all of a sudden, one day it was red, puffy and extremely sore.

I took him to his transplant surgeon and he removed it immediately and packed it. Like yours, it was full of infection. Glad your'e getting it taken care of. I believe they called it a Sebaceous Cyst. You'll do just fine! *Way to go to be your own advocate*
