question: I have this big red bump on my forehead and at first it was just like a hard red bump with a white small dot in the center and now it has a hole in the middle because I popped it and a bunch of soft white/light green thing came out and it was soft and liquids and than it wouldn t stop bleeding until I put ice on it and now it s just red with some white/black on it and it hurts and the whole stretches when I pull my forehead what is this and how do I get rid of it ?
