The brain itself is not sensitive to pain, because it lacks pain-sensitive nerve fibers. Several areas of the head can hurt, including a network of nerves which extends over the scalp and certain nerves in the face, mouth, and throat. The meninges and the blood vessels do have pain perception. Headache often results from traction to or irritation of the meninges and blood vessels. The muscles of the head may similarly be sensitive to pain.

Most of the time it's your muscles in your neck, face, and shoulders that are pulled and/or strained that cause headaches. Sometimes clenching teeth can cause headaches too. Or there are chemical triggers that cause headaches like chocolate, peanuts, MSG, etc. It's a chemical reaction in the brain.

yo uget a headache when the blood vessels in your head expand and contract too fast because of the blood flow.

Do you have a headache right now? Because you don't seem to be speaking correctly. Maybe it's really messing with the part of your brain the deals with speech. hmm....

headaches are caused by a lack of blood flow to the brain, and aspirin thins blood so it will flow easily to the brain.
