Could Dent In Skull Be The Cause For Pressure And Pain In Head?

Hi so I ve been having headache problems every blue moon. The other night my head begins to feel like it had a lot of pressure going on inside of it so I decided to lay down and go to sleep. But when I woke Up the Headache was still there. I felt my head and I felt something that was never there before. It was like a dent but more like a crack in my skull and its pretty long. I just feel a lot of pressure and pain n my head also like blood is being rushed every where. I m 17 by the way and I m really scared.
