Are pains in the head indicative of problems in those specific regions?

Something tells me I’ve asked this before, but I’ve been trawling through my questions and can’t find it!...maybe I’ve just thought about posting before…

When you experience a sharp pain somewhere in your head either with the addition of a headache or without is the pain indicative of a problem in that specific region e.g. behind the eyes, upper right hemisphere, back of the head middle etc.

Knowing that certain parts of the brain perform specific functions but taking into account that no-one has the same neurological set of pathways what do you think… or know?
