Your brain has no pain receptors. The only nine pain sensitive areas around the brain like cranium, muscles, nerves, arteries and veins, subcutaneous tissues, eyes, ears, sinuses and mucous membranes. That means when you have an headache, it comes from one of these nine areas, and not the brain. It has no specific reason and can originate from anything like fatigue and sleep deprivation, stress, the effects of medications and recreational drugs, viral infections and common colds, head injury, rapid ingestion of a very cold food or beverage, dental or sinus issues, and many more.
