Headache indicates any pain localized to the head, of varying intensity and nature. The less popular term to indicate the headache is "cefalgia" (from the greek kefalè meaning head).

The headache is a medical condition that may be one of the symptoms of brain disease or other (fever, stress, ear infections, sinusitis, brain tumors, meningitis, neuralgia), as happens in so-called "secondary headaches" or "symptomatic headaches", but can also be a symptom and disease at the same time, as happens in so-called "primary headaches" or "headaches essential" (which should be considered as real diseases).

The head pain may be more or less intense, continuous or intermittent, occur chronically or episodically and may be accompanied by hypersensitivity to light and sound, nausea, vomiting, watery eyes, more or less widespread. It can affect the entire head or be confined to a specific area of the head.
