We don’t know what causes primary headaches like migraine, tension headaches, and cluster headaches, but we know why they hurt.
For some reason, impulses from your brain cause blood vessels, which sit along the outside of your brain and supply nutrients and oxygen to brain cells, to dilate, or grow wider, like the pupils of your eyes when you’re in dim light.
This dilation agitates the walls of the blood vessels as well as surrounding tissue, and causes these areas to become inflamed. The inflammation is painful and alerts the brain of a threat, and the brain responds by dilating the blood vessels even more. This leads to more agitation, inflammation, and pain, which then leads to further dilation. A vicious cycle is set in motion.
Killing the pain of a primary headache starts with interrupting this vicious cycle by stopping the initial dilation and inflammation in the blood vessels.
