Headaches affect just about everyone at some point and they can present themselves in many different ways. The pain itself may be dull or sharp and may last for anywhere from a few minutes to a few days. Fortunately, very few headaches have serious underlying causes, but those that do require urgent medical attention.
The majority of recurrent headaches are of two types: tension headaches (also called cervicogenic headaches) and migraine headaches. There is a third, less common, type of headaches called a cluster headache that is a cousin to the migraine.
