What is this on my forehead?!?

I have this nickle to quarter size red bump on my forehead that was hurting and itching and it had a noticeable pinhole on it.. And when I got home and squeezed it it was like as if I popped a lot pimples at once (sorry eww I know) every pore on the red bump something came out of it... Is it possible that it was a bug bite?
