question: I have a pea-sized bump on my head. It is hard, but moves with my skin. It hurts to put pressure on it, but not more than if I was putting pressure anywhere else on my skull. It has been there for a couple of years, and I think it may have grown slightly in the last few months. A few areas around it hurt a little bit more than they should, almost as if it has tendrils that hurt whenever the bump hurts too!
