Nine out of ten Americans say that they suffer from headaches. Some of these people experience headaches frequently. Some experience constant headaches that are very painful. These can even make a person nauseous. Ninety-five percent of headaches are tension, migraine, or cluster headaches. These types of headaches are not caused from a disease, but from something in your body that is not sitting correctly.
