It just feels like when I put pressure against my head it affects the inside of the skull, but I guess the body can't differentiate from nerves covering the skull and the inside, in terms of discomfort. So even when it feels like pressure transmiting some kind of weird energy into the inside of my skull it doesn't? It's impossible for the skull to put pressure on the brain without it fracturing then? I read somewhere that the skull can withstand more pressure than the human is capable of putting on it (with their hands of course), so yeah, what I am really worried about is if the skull can move if pressure is put on it, like it suddenly starts bending a bit inward irritating the brain? Or do you literally have to crack your skull for it to change in shape?

EDIT: Isn't a sudden impact resulting in brain shake a type of sudden skull pressure too?
