Most of us get headaches from time to time, but some people have a headache more days than not, and may be suffering from a chronic daily headache. The definition of a chronic daily headache is when you have a headache at least 15 days each month, for at least three months, and the pain is not as a result of another condition.
Most people can get headaches from time to time. Some people are unlucky enough to get a headache nearly every day. Headaches can be caused by a number of different reasons, including lack of sleep or stress. They can also come about after consuming the wrong food or drink, or too much, or too little, of either.
