Generally speaking, headaches are any pain associated with any head region area, be it the face, skull, or neck. However, there are several kinds of “common” headaches, each with its own set of pain triggers and treatment plans.
A headache can be “primary,” meaning that the headache is the issue all by itself without any underlying cause. If a headache is considered “secondary,” this means your headache is a symptom of another condition, for example, a misaligned spine.
