A headache is a pain in the head or face, often described as a constant, sharp, or dull throbbing pressure. Headaches can vary considerably in type, intensity, location, and frequency.

Headaches are a very common condition that most people experience several times throughout their lives. They are the most common type of pain and a leading cause of missed work or school visits, as well as doctor visits.

Although most headaches are not dangerous, some can be a sign of a more serious condition.

There are more than 150 types of headaches. They are divided into two main categories: primary and secondary headaches.
