I started to grow a zit like bump on my cheek, but instead of growing a white head, staying skin color or taking a red inflamed color, it started to look like a bruise. Like if I had been punched in the cheek repeatedly. It had grown the size of about 2 inches. I rubbed my hand across my face and I felt a popping sensation inside the area. It had felt as if a zit had popped but had happened under the skin. I decided (and I know I probably shouldn't have) to try and squeeze it to see if anything else would pop. I had felt many other pops but nothing had surfaced, then after a few more squeezes (and I had not applied a lot of pressure for each squeeze, very minimal) it had popped, and a mix of the white nasties from zits and a lot of blood shot out of an opening like a fountain. It had also released a lot of pressurised air, and I could hear it as it escaped my cheek. It has been a day and I have just recently touched it, all the popping sensations are back and if I touch it again I can feel the pops again. What is this and why is it happening?
