Hi..... Headaches are generally classified by cause: Primary headaches A primary headache is caused by problems with or overactivity of pain-sensitive structures in your head. A primary headache isn't a symptom of an underlying disease... secondary headache is a symptom of a disease that can activate the pain-sensitive nerves of the head. Any number of conditions — varying greatly in severity — may cause secondary headaches. Consult Neurologist....
