What are headaches?
A headache is pain in any part of your head. Just about everyone has had a headache, but the types, causes and symptoms of headaches vary widely. They can happen to one or both sides of your head, be in one location, radiate across your head from one point, or have a viselike quality. The level of pain can vary from mild to a sharp throbbing sensation, and last for less than an hour to several days. Some headaches develop slowly; others can quickly feel like a knife has been thrust into your brain. While most headaches go away on their own, some signal a serious health condition. Always take seriously any new headache or severe headache that lasts more than two weeks. It may be a warning sign of a serious health problem.
