this is the causes of the headaches..hope u enjoy it..
There are two types of headaches: primary headaches and secondary
headaches. Primary headaches are not associated with (caused by) other
diseases. Examples of primary headaches are migraine headaches,
tension headaches, and cluster headaches. Secondary headaches are
caused by associated disease. The associated disease may be minor or
serious and life threatening.
How common are primary and secondary headaches?
Tension headaches are the most common type of primary headache; as
many as 90% of adults have had or will have tension headaches. Tension
headaches are more common among women than men.
Migraine headaches are the second most common type of primary
headache. An estimated 28 million people in the United States (about
12% of the population) will experience migraine headaches. Migraine
headaches affect children as well as adults. Before puberty, boys and
girls are affected equally by migraine headaches, but after puberty,
more women than men are affected. An estimated 6% of men and up to 18%
of women will experience a migraine headache.
In the United States, migraine headaches often go undiagnosed or are
misdiagnosed as tension or sinus headaches. As a result, many migraine
sufferers do not receive effective treatment.
