Headaches affect just about everyone at some point and they can present themselves in many different ways. Some people only experience pain in one part of their head or behind their eyes, some people experience a pounding sensation inside their whole head, and some people even experience nausea, while others do not. 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.
Although headaches can be due to a wide variety of causes, such as drug reactions, temporomandibular joint dysfunction (TMJ), tightness in the neck muscles, low blood sugar, high blood pressure, stress and fatigue, 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.
