On the top (a little to the left) of my head, it hurts really bad, to touch, or when my hair moves, or I cough .... Like someone hit me in the head with a baseball bat, or I hit my head on something, which neither has happened. It hurts at the littlest touch. But it s not a head ache....I have had 3 people look at my head, and there is nothing there, no bump, no bruise , its not even red. What could this be?
