I'm 24 yrs old and within the last 2 years or so I have noticed that the right side of my head above my temple seems to be indented. It's a lot different from the other side and it almost feels like a shelf that extends about two inches towards the back of my head. I haven't noticed it until this point but I know for sure from pictures it has not always been like this. I also suffer from a receeding hairline that is much more noticeable on that side.
I have been researching and researching answers to my skull change and have yet to figure out if I should be concerned or not. I'm currently in the military overseas so my options tomget checked out are limited. Thank you all in advance for your help.
