Headaches

What Causes Headaches?

Headaches can be primary and secondary. Primary headaches do not result from some other health condition.

The most common type of primary headache is caused by problems with the neck muscles. Changes in the blood vessels inside the skull usually cause migraines. Other common types of headache include “cluster” headaches—headaches grouped together over weeks at a time; sinus headaches, associated with allergies and/or sinus infection; and headaches from poor vision.

Secondary headache results from some other cause or condition—head injury, concussion, blood vessel problems, or high blood pressure—or from side effects of some medications, infections in the head or sinuses or elsewhere in the body. Rare headache causes include tumors, aneurysms and other abnormal growths inside the skull, and toxic substances in the blood. Certain foods, such as monosodium glutamate (MSG), a food flavor enhancer, may cause headaches, as well.
