By mere accident I felt on the left side on the top of my skull something like a little bump or a tiny dent. I have no idea if this has been there always, ( or for a long time), but I think there is no symmetrical thing on the other side. I am freaking out. It does not hurt or anything, it is hard to find, but now I know it is there and I keep on feeling for it and touching it. Is it worth going to the doctors? Please reply if you have similar things on your skull. Thank you.
