Headache

This review was developed as part of a debate, and takes the "pro" stance that abnormalities of structures in the neck can be a significant source of headache. The argument for this is developed from a review of the medical literature, and is made in 5 steps. It is clear that the cervical region contains many pain-sensitive structures, and that these are prone to injury. ⋯ Clinical studies have shown that pain from cervical spine structures can in fact be referred to the head. Finally, clinical treatment trials involving patients with proven painful disorders of upper cervical zygapophysial joints have shown significant headache relief with treatment directed at cervical pain generators. In conclusion, painful disorders of the neck can give rise to headache, and the challenge is to identify these patients and treat them successfully.

Cervicogenic headache (CeH) is a well-recognized headache syndrome, distinguishable from other primary and secondary headaches. Although in some cases a cervical lesion may be detected in connection with the headache, many CeH patients have no demonstrable lesion. ⋯ This suggests that the neck is not an independent headache generator. CeH may depend in addition on a central predisposition counterpart, leading to the activation of the trigeminovascular system and pain generation.
