Headaches are painful and occur in the head. Headaches occur due to a primary or secondary cause. Primary headaches, such as migraines or tension headaches, are among the most common headaches that lead people to seek medical attention. This type of headache is not a symptom of a disease, but a disease in its own right. It is a "primary" headache because it is the main concern. Stress and sleep disturbances often cause these headaches.
