Headache and migraine are one of the most common forms of pain. Usually, the headache occurs spasmodically. The most frequent forms are a migraine or a headache. Both chronic and reverting headaches can cause pain and distress, but it is rare that they reflect a serious health problem. However, any change in the pattern or nature of a headache could be the symptom of a serious problem (for example, a pain that was sporadic change to frequent, or from mild to acute), and for this reason, it should be referred to medical care as soon as possible.
