Seeligmüller38 speaks very highly of the effect of the nasal douche, used for the sake of curing the catarrh of the frontal sinuses, and potassic iodide may be useful by rendering the secretions more fluid.

THE EPILEPTIFORM FACIAL NEURALGIA, OR TIC DOULOUREUX, is a chronic affliction, characterized by the suddenness of onset and the severity of its paroxysms of pain, which may recur every few minutes with lightning-like rapidity, either spontaneously or brought on by motion of the jaw or the taking of food, and disappear again as quickly. After a group of such paroxysms as this there may be an intermission of some hours or days. During the attack the patient is apt to rub the seat of pain with great violence. The path pursued by the darts of pain may be either in the direction of the nerve-trunks or in an irregularly inverse direction.

In spite of their sufferings, these patients may present an appearance of health. In its worst forms, and especially in advanced life, this variety of neuralgia may be incurable, and at the best it is sure to tax the care and skill of the physician. Anstie thinks that it is apt to be associated with a taint of insanity.

The best TREATMENT consists in the most painstaking attention to hygiene, in the persistent use of galvanism, arsenic, cod-liver oil, quinine, aconite (see under General Treatment), and phosphorus. Croton chloral is occasionally of service.

As a last resort, surgical measures (see above) may be appealed to, but it should be borne in mind that even when the prospect seems most hopeless the relief under medicinal and hygienic treatment may really be near at hand. Where section of nerves is without result, the operation of tying the larger vessels, the carotid or vertebral, on the affected side may be tried, and offers some chance of success.

OCCIPITAL AND CERVICO-OCCIPITAL NEURALGIAS are second only to trigeminal neuralgia in severity, though, fortunately, less common, and either is liable by extension to give rise to the other.

Neuralgic pains in the occipital region may attend Potts's disease of the cervical vertebræ; and this is especially important to bear in mind because the osseous deformity is often wanting for a long time.

The writer has known a persistent pain in this region to be due to intracranial syphilitic disease, and to cease suddenly with the advent of more serious cerebral symptoms.

CERVICO-BRACHIAL AND BRACHIAL NEURALGIAS are less often indicative of the neuropathic taint than the facial neuralgias; and, on the other hand, they are, like sciatica, relatively often due to neuritis set up by injury, amputation, strains, enlarged cervical glands, periarthritis of the shoulder,39 etc., or associated with herpes zoster. When not due to an unremovable cause the prognosis is favorable. The treatment needs no special description.
