                                Headache is one of the most common types of recurrent pain as well as one of the most frequent symptoms in neurology. In addition to occasional headaches, there are well-defined headache disorders that vary in incidence, prevalence and duration and can be divided into two broad categories. In secondary headache disorders, headaches are attributed to another condition, such as brain tumour or head injury; for the primary disorders the headache is not due to another condition.
