Hi tmacd11,
Interestingly neither the brain tissue or bones of your skull contain any pain detectors so headaches are caused by other parts of the brain. The blood vessels which supply your brain and the skin on your scalp are very sensitive to pain. Headaches are usually caused by something that has changed the flow of blood in your brain. A tension headache can be caused by constant stretching of muscles in the neck.
Nobody really knows the biology behind headaches – we are starting to understand more but there is still much more to discover!

Hmm, wish I could add to this answer but Gemma’s right. There are actually all sorts of reasons behind headaches, what’s key is that some headaches are the direct or ‘primary’ problem, caused by tension or stress.
Other headaches are a side-effect, or ‘secondary’ problem of a much larger health issue. such as a tumour. These are very rare. Most headaches primary types of headaches.
There a lots of details we could go into about headaches, but it depends how much you much you want to know??
