Hello, fellow dented-head people! A couple of days ago I discovered a dent on the top right side of my head about 2 inches back from my hairline and about 2-3 inches long extending toward the back of my head. It is coincidentally along my hair part and is about 1/4" wide.
Anyway, I think Heddy (who commented on page 2) is onto something with the sunglasses theory! I have been periodically wearing my sunglasses on my head this week and just put them on and ran them back and forth on the top of my head. Wouldn't ya know it, it rubbed right along my dent! The only thing that doesn't quite make sense is that I've often worn my sunglasses on my head throughout my life and never had this "problem".
I think that if you have a pain-free dent (not accompanied by migraines, dizziness, tingling, etc.) you shouldn't worry too much about it. Of course if there are other symptoms, you should seek medical help. I Googled my head dent out of sheer curiosity and am hoping that I'm right about it just being from my sunglasses.
For those of you looking for similarities in dented head cases, I'm a 26 year old female living in an arid climate who does wear sunglasses on my head. I don't think I'm dehydrated and have no reason to believe I'm gluten intolerant. I've noticed a fair amount of young women who posted in this forum and know that many young women wear sunglasses on their head like me.
Good luck to all of you looking for answers! I'll post an update if I have any news.
