Headache: Brain
built 255 days ago
What hurts when you have a headache? The bones of the skull and tissues of the brain itself never hurt because they lack pain-sensitive nerve fibers. Several areas of the head can hurt, including a network of nerves that extends over the scalp and certain nerves in the face, mouth, and throat. Also sensitive to pain (because they contain delicate nerve fibers) are the muscles of the head and blood vessels found along the surface of the brain, as well as at the base of the brain.

There is less oxygen going into your brain, which may trigger a headache. The temperature of food can ... trigger a headache. Remember taking large bites of really cold ice cream and remember those ice cream headaches? If you get headaches easily, you might have to take smaller bites of ice cream or make sure you warm up your mouth before you take another bite.

Nearly everyone has experienced a headache at some point in their lifetime, and typically it goes away within a few hours, or in the worst case scenario, a few days. When you have a nasty headache, the best feeling in the world is getting rid of it. Aside from obvious ailments such as brain tumors and other serious head injuries, chronic headaches can affect anyone for a multitude of reasons.

Although it may feel like it, a headache is not actually a pain in your brain. The brain tells you when other parts of your body hurt, but it can't feel pain itself.
