According to the National Headache Foundation, over 45 million Americans suffer from chronic, recurring headaches and of these, 28 million suffer from migraines. About 20% of children and adolescents also have significant headaches. One of the most common reasons for headaches may be untreated whiplash injuries from automobile accidents.

Below is a list of the most common types of headaches.
Tension headaches: Also called chronic daily headaches or chronic non-progressive headaches, tension headaches are the most common type of headaches among adults and adolescents. These muscle contraction headaches cause mild to moderate pain and come and go over a prolonged period of time.
Mixed headache syndrome: Also called transformed migraines, this is a combination of migraine and tension headaches. Both adults and children experience this type of headache.
Cluster headaches: The least common, although the most severe, type of primary headache, the pain of a cluster headache is intense and may be described as having a burning or piercing quality that is throbbing or constant. The pain is so severe that most cluster headache sufferers cannot sit still and will often pace during an attack. The pain is located behind one eye or in the eye region, without changing sides. The term "cluster headache" refers to headaches that have a characteristic grouping of attacks. Cluster headaches occur one to three times per day during a cluster period, which may last 2 weeks to 3 months. The headaches may disappear completely (go into "remission") for months or years, only to recur.
Sinus headaches: Sinus headaches are associated with a deep and constant pain in the cheekbones, forehead or bridge of the nose. The pain usually intensifies with sudden head movement or straining and usually occurs with other sinus symptoms, such as nasal discharge, feeling of fullness in the ears, fever, and facial swelling.
Acute headaches: Seen in children, these are headaches that occur suddenly and for the first time and have symptoms that subside after a relatively short period of time. Acute headaches most commonly result in a visit to the pediatrician's office and/or the emergency room. If there are no neurological signs or symptoms, the most common cause for acute headaches in children and adolescents is a respiratory or sinus infection.
Hormone headaches: Headaches in women are often associated with changing hormone levels that occur during menstruation, pregnancy, and menopause. Chemically induced hormone changes, such as with birth control pills, also trigger headaches in some women.
Chronic progressive headaches: Also called traction or inflammatory headaches, chronic progressive headaches get worse and happen more often over time. These are the least common type of a headache, accounting for less than 5% of all headaches in adults and less than 2% of all headaches in kids. Chronic progressive headaches may be the result of an illness or disorder of the brain or skull. Some studies have shown that hereditary may play a role in certain headaches especially migraines.
Headache pain results from signals interacting between the brain, blood vessels, and surrounding nerves. During a headache, specific nerves of the blood vessels and head muscles are activated and send pain signals to the brain. It's not clear, however, why these signals are activated in the first place. There is a migraine "pain center" or generator in the mid-brain area. A migraine begins when hyperactive nerve cells send out impulses to the blood vessels, causing constriction, followed by the dilation of these vessels and the release of prostaglandins, serotonin, and other inflammatory substances that cause the pulsation to be painful. Serotonin is a naturally occurring chemical essential for certain body processes.
Other causes of tension headaches include eyestrain and neck or back strain due to poor posture.
