Headaches.-- Headaches, aside from those of acute illness, may be roughly divided into three classes: first, those which are due to indigestion; second, neuralgic headaches; and, third, those due to pelvic inflammations. The headaches due to indigestion are usually located over the eyes and all over the forehead; they are more or less constant and are accompanied by other symptoms of indigestion, and very often by constipation. The feces are allowed to remain in the bowels overlong, the toxic matters are taken up by the blood, and headaches and vertigo result. Neuralgic headaches are of an entirely different character; the pains are here of a lancinating character, and are not confined to any one region of the head. As a rule, they are accompanied by neuralgic pains in other parts of the body. Neuralgia generally means a rundown state of the system from overwork, worry, or malaria, and tonics and cod-deliver oil are indicated. A constant dull pain on the top of the head or in the back of the neck generally indicates some uterine inflammation, and can only be cured by removing the cause. In any case it is very evident that taking the various "headache powders" with which the market is flooded will never cure the woman of her headaches; and many of these powders are very dangerous, especially where the heart is weak, as most of them are heart-depressants. Fainting.-- Fainting may be due to a weak heart, to heart disease, or to sudden shock, as on receiving a bad piece of news; during pregnancy the close air of a room may cause a woman to faint. The first thing to be done is to lay the woman down on the floor or bed with nothing under her head; loosen all her clothes about the neck and waist, and throw the windows open so that she will get plenty of fresh air. If she is able to drink, give her one teaspoonful of aromatic spirits of ammonia in four tablespoonfuls of cold water. If the feet are cold, place hot-water bottles to them to improve the circulation. And if at the end of fifteen minutes she does not show signs of decided improvement, give her two tablespoonfuls of whisky in an equal quantity of hot water. In the meantime the physician will have been summoned. These attacks of fainting often occur in a crowded ball-room, and are due to tight lacing and the poor ventilation of the room.
