Headache in pregnancy is caused either by uterine irritation, by derangement in digestion, or by both combined. If caused by uterine irritation, there will be burning pain in the top of the head or at the base of the brain, accompanied by great soreness, which the patient describes as a _sore pain_. This pain, too, is constant, and likely to affect both vision and memory. It usually increases toward evening, and is relieved by lying down. For this, take warm sitz baths daily, apply hot fomentations to back of the head, and keep in a reclining position as much as possible. (See Chap. XXI.) SICK HEADACHE is a severe pain in the forehead and through the temples, accompanied by nausea and vomiting, often, too, by coldness of the extremities and great prostration. The attacks are irregular in frequency and duration. The causes are indigestion, biliousness, constipation, fatigue, anxiety, etc. One under ordinary circumstances _ought to be ashamed to have sick headache_. A little _common sense_ in the methods of living will do away with the causes. TEA-DRINKING as a habit has much to do in producing headaches. Tea is stimulating. One ever so weary, after drinking a cup of tea, feels as _good as new_, is invigorated, hopeful, chatty, and entertaining. The social cup of tea! Has it really restored wasted tissues? Is it a genuine nerve feeder? Or does it stimulate native forces to greater action? Is it like a whip to the fagged horse, spurring it on to more toil? Very little tea is appropriated to build up worn-out tissues. It gives false strength. In the reaction headache ensues. It is the penalty that follows over-wrought vitality. Dr. Gregg’s article in the _Homeopathic Quarterly_ on tea as a cause of sick headache is worthy of the attention of those who suffer with this common malady. The doctor alleges that this beverage is the cause of this disease more than all other causes put together, and gives a number of instances where, after leaving off its use, persons who had previously been afflicted were exempt from further attacks. One evidence the doctor gives of the injurious effect of this agent is the fact that tea-drinkers are liable to have headaches if they omit its use at the regular times of taking it, and that the pain ceases on again resuming the cups. “This latter, with many other facts contained in the article, has often been observed,” says the doctor, “not only on myself but on others, for I had inherited the disease from my mother. It had been the plague of her life as well as my own. We had both been not excessive but regular tea-drinkers; and although she lived to be over eighty years of age, she was never exempt from an attack of greater or less severity, for more than a few weeks at a time, for a period of nearly or quite half a century.
