Causes of Headaches | 
|
| There are two types of headaches: |
Primary Headaches include tension, migraine, cervicogenic, and cluster headaches and are not caused by other underlying medical conditions. More than 90% of headaches are primary.
Secondary Headaches result from other medical conditions, such as infection or increased pressure in the skull due to a tumor. These account for fewer than 10% of all headaches. |
| Descriptions of the Primary Headache Types: |
1. Tension Headaches: are the most common, affecting more than 75% of all headache sufferers. As many as 90% of adults have had tension headaches.
 Tension headaches usually involve a steady ache, rather than a throbbing one, are described as a feeling of pressure or tightening, may last minutes to days, affect both sides of the head, and and do not worsen with routine physical activity. It may also be accompanied by hypersensitivity to light and noise. Some people get tension (and migraine) headaches because of stressful events. Tension headaches may also be chronic, occurring frequently or daily
Rebound Headache: Rebound headaches may occur among people with tension headaches, as well as in those with migraines. It can be the result of taking prescription or nonprescription pain relievers daily or almost every day, contrary to directions on the package label. If prescription or nonprescription pain relievers are overused, headaches may 'rebound' as the last dose wears off--leading you to take more and more pills. This is a great reason to call your chiropractor. Break that cycle! | | If you think you are experiencing Tension or Rebound Headaches, click here now. |
| 2. Cervicogenic Headaches: Cervicogenic Headaches come from disorders of the neck. They are often brought on by neck movement and/or sustained awkward head positioning (such as painting the ceiling or washing the floor). There may also be stiffness in the neck or shoulder and arm pain accompanying the headaches. | | If you think you are experiencing Cervicogenic Headaches, click here now. |
3. Migraine Headaches: Migraine Headaches are less common than tension headaches, but still afflict 25 to 30 million people in the United States As many as 6% of all men, and up to 18% of all women experience a migraine headache at some time.
Migraines may last 4-72 hours and involve the entire head. They can cause throbbing and are aggravated by routine physical activity.
Nausea, sensitivity to light and sound often accompany migraines. An "aura" may occur before head pain begins-- involving a disturbance in vision, and/or an experience of brightly colored or blinking lights in a pattern that moves across the field of vision. About one in five migraine sufferers experiences an aura.
Usually, migraine attacks are occasional, or sometimes as often as once or twice a week, but rarely occur daily. | | If you think you are experiencing Migraine Headaches, click here now. |
4. Cluster Headaches: are pretty rare, affecting about 1% of the population. They are different from migraine and tension headaches. Most cluster headache sufferers are male -- about 85%.
Cluster headaches come in groups or clusters lasting weeks or month. The pain is extremely severe but the attack is brief, lasting no more than a hour or two. The pain centers around one eye, and this eye may be inflamed and watery. There may also be nasal congestion on the affected side of the face.
These "alarm clock" headaches may strike in the middle of the night, and often occur at about the same time each day during the course of a cluster. A history of heavy smoking and drinking is common, and alcohol often triggers attacks. | | If you think you are experiencing Cluster Headaches, click here now. |
