Is a headache where i think it is?

When i feel a headache in a certain part of head is it actually there or could it be happening in another part of my brain?

The brain itself has no pain receptors and cannot feel pain. Rather, headaches are things like blood vessels around your skull hurting. While it's true that you could be imagining pain, most headaches are actual pain receptors, even if their ability to sense pain is heightened from a purely psychological reason like stress.
