Hi I have indentations in my skull. English is not my first language, so I hope I can write properly the things I want to say. I am 36. I noticed them a few days ago. I was terrified, I thought my head was opening haha! So I asked to my father who is a surgeon. He told me that he has indentations too. And so his mother. It's weird. And they never felt nothing, no migraine, nothing. He doesn't know about the name of this condition, but it's real and it's not dangerous.
