I don't know the right name for these, I've only got two or three of them ever, but they left some big weird lilac spots on my hips, that look like hematomas. They appear to be pink and big when they are new, they look somewhat like acne conglobata if that was just for one pimple. If you pop them (I always pop everything I can), you get lots of blood flowing out and then in a few days it goes away and all you see is just that big lilac spot which is ugly. One of them, the oldest I had, transformed into a mole, the other is about to fade away, and one more I can't find.
Just wondering what could it be and maybe someone else has had it. Will appreciate any info on this, thanks.
