It s a bit hard to explain, but I have some sort of ridge on top of my head. It s as if my skull comes up to a long, point. Also, on the lower back on my skull, I have this bump. This bump is definitely apart of my skull and is actually bone. My dad has the same thing, nearly identical to what I have. How could this come about? I have another more neurological question: Because of these weird deformations on my head (more so the ridge on top of my head) could this have an effect on my parietal lobe growth and how it function?
