Headache is a common symptom in patients suffering from cervical spine disorders. The percentage of headaches in association with degenerative changes of the cervical spine ranges from 13 to 79% and that in association with indirect trauma of the cervical spine from 48 to 82%. Based on neuroanatomical and neurophysiological studies, the relationship of the upper cervical spine and the trigeminal nuclei has been demonstrated and serves as an explanation for perceived head pain in cervical spine disorders. ⋯ In 1983, Sjaastad et al. postulated the concept of 'cervicogenic headaches': a migraine-like headache due to certain disorders of the cervical spine, strictly located unilaterally, its manifestations being in the temporal, frontal, and ocular areas, with associated symptoms such as slight lacrimation, conjunctival injections, tinnitus, runny nose, and erythema in the forehead ipsilaterally. As arguments in favour of a cervical origin, Sjaastad mentioned the following features: precipitation of the headaches either by neck movements or by pressure against certain tender spots on the neck, the possibility of homolateral shoulder or arm pain, stiffness and pain of the neck, and reduced mobility of the cervical spine. In 1988, the Headache Classification Committee of the International Headache Society set strict criteria for 'headaches' to be classified as to be of cervical origin.

The hallmark of trigeminal neuralgia is the abrupt onset of short pains in the face or in a part of the face, described as stabbing, lightning or electric shocks. Attacks are often triggered by cutaneous stimuli to the face or the oral cavity, which may be such minor activities as talking, chewing, brushing the teeth, or even wind blowing on the face. As a result, facial hygiene as well as a good diet may be neglected. ⋯ If the trigeminal neuralgia may be considered as a nerve irritation, like the glossopharyngeal neuralgia and the nasociliary neuralgia, nerve lesion may elicit neurogenic or neuropathic pain, characterized by chronic burning pain; post-zoster pain, iatrogenic and posttraumatic pain illustrate this condition. Cluster headache (Horton neuralgia), Sluder's neuralgia and auriculotemporal neuralgia may be related to a dysfunction of the autonomous nervous system. Finally, lesion in the mandibular joint may cause unilateral facial pain.

Migraine is caused by intermittent brain dysfunction. Attacks result in severe unilateral headache with nausea, vomiting, photophobia, phonophobia and general weakness. The prevalence of migraine is 12 to 20% in women and 8 to 12% in man. ⋯ Substances of second choice are valproic acid, DHE, pizotifen, methysergide and magnesium. Homeopathic remedies are not superior to placebo. Nonpharmacological treatment consists of sport therapy and muscle relaxation techniques.

Headache, facial pain and toothache are poorly localized and irradiate in distant areas. Thus, toothache often causes facial pain and headache, but, in turn, it can also be mimicked by several forms of these disorders, in particular by a myoarthropathy of the masticatory system, a migraine, a tension-type headache, a neuropatic pain and a trigeminal neuralgia. The atypical odontalgia is a nonodontogenic form of toothache that is difficult to diagnose; therefore, it leads to a number of invasive dental procedures which normally worsen the pain condition. ⋯ The burning-mouth syndrome is an other poorly understood form of intraoral pain that occurs primarily in postmenopausal females. Several etiologic factors have been described, but treatment based on one or more of these factors is often ineffective. Spontaneous remission occurs in about half of the patients after several years.
