This form is characterized by a throbbing, splitting pain in the temples. The patient also feels sickness at the stomach, and generally vomits a large quantity of undigested food followed by bile, before relief is obtained. It is caused by errors in diet. Persons who suffer from this form of headache, habitually, are subject to bilious dyspepsia, and should follow the directions for treatment prescribed for that disease. Generally relief may be obtained by hot fomentations to the head, followed by tepid compresses, hot fomentations over the stomach and bowels, and hot drinks. When the bowels are constipated, as they generally are, the patient should take a large warm water enema. When possible to do so, warm sitz and full baths should be taken, as great relief is generally afforded by these means. Patients subject to bilious headache should avoid the use of tea, coffee, fats of all kinds, tobacco and spirituous liquors, which are among the most positive causes of the disease.

Nervous Headache

This form of headache closely resembles the preceding in its symptoms, but is generally confined to one side of the head. It is elsewhere described under the head of hemicrania, or migraine, which see for treatment, etc.
