ABSTRACT

In order to understand Chantal’s complaint of headache, we need to know which structures of the head and in the interior of the skull are pain sensitive . Pain can originate from any of the structures of the head, including the skin, teeth, mucous membranes (including the gums), the sinuses, and from the eye and orbit . The brain itself has no pain fibers, but the brain coverings, the meninges, are pain sensitive, as are the walls of the major cerebral blood vessels . Any

irritation (infection, blood) or stretching (pulling) on the meninges or cerebral vessels will give rise to pain .
