It's been there for a really long time, and i haven't been able to pop it. It's been really hard and almost purpleish gray color. The pimple was relatively small but still bothered me, whenever i could try to pop it, nothing would happen, but finally today it was flaking so i picked at it and then after a big sqeeze a small roundish hard thing came out. No puss or anything, it bled a little afterwards but thats it. This thing whatever it is, is hard as a rock. What I want to know is what the heck it is... and is this "normal"? Thanks for your help in advanced, and sorry if this is gross.
