Why the hell does my hair hurt?

Wow. I see someone asked this same Q in 2008.

Obviously my HAIR doesn’t hurt, but it hurts at the roots if I run my hand through my hair or wash it. It’s only in one spot, just to the left of the center line and doesn’t go over the center. It is so weird. If feels like some one has been pulling the crap out of my hair or something.
I started noticing it a couple of months ago.
