A friend of mine had a large sore spot on the top of her head. It kept getting bigger and more sore. Her husband pushed on it to see if anything would come out. She said it bled unreal. It was like a noise bleed. After blood and a bunch of pus came out, this hard bone-like particle came out of the spot and left like a whole in her head. She said it looked almost like an eye tooth. What could this be?
