"Headache"

Headache is the general term used to describe pain associated with the forehead, skull, neck, temples, and/or face. The pain can be pulsing, steady, abrupt, dull, throbbing, one-sided, or all over.

Headache pain is caused by different factors, including blood vessel dilation, muscle tension, and nerve inflammation/irritation.

Headache triggers include stress, certain foods, certain beverages, lack of sleep, medications, poor posture, bright or poor lighting, intolerable sounds, and sharp smells.
