I randomly started feeling around my head and have noticed that there are a few dents and one little like bony bump on the leftish side. I cant remember if they've always been there because I never really throughly checked my head. Like when I wash it, I don't feel it so it could've been always been there. Does anyone else have like dents or most importantly bony bumps on their skulll?? I genuinely thought they're supposed to be smooth. please help
