Every adult has experienced a headache at some point. However, headaches vary greatly in frequency and severity. Most people can self-diagnose their own headaches and often turn to over-the-counter medications to help relieve the pain. However, doctors do not have any set of tests to diagnose headache types and causes. Instead, they mostly rely on the description that patients give them, and typically, the descriptions of the symptoms of headache pains vary wildly.

Headaches are a common occurrence in our society; in fact, each one of us has experienced a headache at one time or another. However, there is still so much that we do not understand about headache types and causes. While we know some of the triggers, it is hard to pinpoint the exact cause of many types of headaches. There are so many variables as well as degrees of pain associated with the different types that studying them is very difficult.
