Headaches are a common cause of suffering.A headache is a condition of pain in the head; sometimes neck or upper back pain may also be interpreted as a headache. It ranks amongst the most common local pain complaints.

What are the causes of headaches?
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. ( Hm.. I think I also get headache now from tension..)
Migraine headaches are the second most common type of primary headache. 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.
As a result, many migraine sufferers do not receive effective treatment. Cluster headaches are a rare type primary headache, affecting 0.1% of the population. An estimated 85% of cluster headache sufferers are men. The average age of cluster headache sufferers is 28-30 years, although headaches may begin in childhood.
Secondary Headaches have diverse causes, ranging from serious and life threatening conditions such as brain tumors, strokes, meningitis, and subarachnoid hemorrhages to less serious but common conditions such as withdrawal from caffeine and discontinuation of analgesics.
