An inrteresting question! The main reason for headaches is tension and sometimes dehydration after alcohol or long periods in the sun) The tension puts the nerves under a sort of strain and they become tired and in doing so tend to misfire and give of pain signals which is relayed to the pain centre in the brain. The blood vessels also dilate or stretch and this affects the nerves so they give off signal that indicate stress and interpretes to the brain as a pain. In the dehydration event it is reduced fluid in the body that changes the electrolyte balance causing the nerves to misfire once again and scramble signals that alert the pain center in the brain that something is not right This resultys in the mind registering pain Usually behined the eyes and the head itself. Blood vessels are also involved. Quite often the intake of fluid back into the system restires the swollen bllod vessels back to normal and thus reduces the stretching on the nerves
That is ther simplified version. It is much more complicated for a non medical person to follow But that should give you a fair answer

When you have a headache it's due to the blood vessels in your skull and around your brain dilating or getting wider. Becuase the brain and the blood vessels that feed it are inclosed in the skull which is (for the most part) a solid plate, when vessels dilate there is no place for intercranial preasure to be relieved. The pain you feel is a result of that preasure inside your head from veins and arteries dilating and pressing against the cranial walls. Things like smoking and certain drugs (Nitro) will cause vessels to dilate and things like caffiene and drugs like Epinepherine will cause the vessels to constrict.

Headache is usually a sign of increased intracranial pressure or high blood pressure which also increases your intracranial pressures. Take some panadol.

i dont know exactly what hurts, but i know its not the brain the brain has no pain receptors if it did it would be impossible to do brain surgery's the pain would kill you, its probably just pressure on the nerves in your skull your skull
