There are no nocireceptors (those that perceive pain) in the nervous tissue of the brain. They are present either in the membranes of the brain or in the vessels.

The main reason for the irritation of these receptors is the pressure that occurs when the actual blood pressure in the vessels or pressure arises on the vessels and tissues.

Another reason for headaches is damage to the nerves and centers themselves.

These are, let's say, two "big" reasons. More specifically, there are dozens and hundreds of such reasons.

The first group (associated with changes in pressure on tissues and blood vessels) includes: hypertension, hypotension, traumatic brain injury, tumors, spasms vessels (with migraines, VSD), problems with the inflow and outflow of cerebrospinal fluid, inflammation of the meninges, sinusitis, frontal sinusitis, infectious foci, changes in blood pressure when the composition of the atmosphere changes (increase / decrease in the amount of oxygen, the presence of carbon monoxide, etc.)

The second group includes lesions of pain centers (not important as a result of injury or stroke), neuralgia of the cranial nerves, osteochondrosis of the cervical spine. Moreover, the second reason can lead to the first: when the nerves are damaged, the work of those organs that he innervated is disrupted. In the case of nerves that regulate the lumen of blood vessels in the brain or the work of the heart, we first receive a signal that a nerve is transmitted (in osteochondrosis, for example), and then a signal that we have problems with blood vessels and pressure.

In general, there are many reasons for headaches and each requires a very special treatment, which should be prescribed by a doctor, and not by Internet advisors.
