I had a fatty cyst that just looked like a normal skin colored bump, tumor like, finally get infected (my body fighting it off) and it was a really crazy process. It turned bright red and got bigger, like big enough to see through my shirt, then it started to leak clear, kind of chemical smelling stuff when I would do anything physical. Then, it just kind of opened up on its own.
It was in a place on my shoulder where I could press my hand down on the counter, and lean into it to make it empty. It came out in inch+ high towers, and out of two seperate holes. I pressed white fatty stuff out over and over.
I had had it emptied at the doctors once before, but it came back. Only mistake I made was going to the doctor AFTER it was 99% empty; he just cut into it to get paid. Now it's discolored.
