A primary headache is caused by dysfunction or overactivity of pain-sensitive
features in the head, and isn't a symptom of an underlying disease.
Chemical activity in the brain, the nerves or blood vessels of your head
outside the skull, or muscles of the head and neck — or some combination
of these factors — may play a role in primary headaches. Some people
may carry genes that make them more likely to develop such headaches.

Migraine (with and without aura)
Tension headache (medically known as tension-type headache)

of intense pain. Cluster headaches are one of the most painful types of
headaches. They often strike in cyclical patterns. The person will have
frequent bouts of cluster headaches, and then the headaches will stop
completely for a period of time.
