Headaches are a common problem in todays society and in the computer era. Headaches have increased in frequency and many adults in the United States have at least one bad headache every month. In a survey of more than 1 million individuals in the general population, headaches were the most frequent current physical complaint among men and women. In a report of lifetime headache histories, 41% of men and 50% of women experienced severe headaches that rendered them unable to work.
For most people, headaches get better with rest and over-the-counter medications, however, for others, headaches occur so frequently or are so severe that they interfere with the normal activities of daily life.
There are many types of headaches, but the three most common are migraine headaches, tension headaches and neck related headaches (cervicogenic).
