Sudden redness of the cheeks indicates meningeal inflammation.

The well-known cheek flush of tuberculosis should not be confounded with nervous flush.

Red cheeks of teething children will be accompanied with other signs of teething.

Red cheeks and a white line around the mouth and nose indicate irritation of the stomach; in children, gastric fever, if there is vomiting. These symptoms may precede the eruptive fevers.

Cold, blanched feet and hands indicate vasomotor constriction and have intestinal putrefaction as their cause. When this condition becomes pronounced, it is called syncope of the limbs. The patient may have "dead finger"--a finger or fingers without feeling--and there may develop points of gangrene; or there may be the opposite state--venous congestion or cyanosis, such as occurs in asphyxia--oxygen starvation. The source of toxin poisoning must be discovered and removed, or this state cannot be overcome.

Acute vasomotor disturbances cause hyperemia of the breasts in women. It is too common to amputate the mammary glands, the surgeon diagnosing fluxions as cancer. The careful physician will find an accompanying uterine disease, which, if cured, will do away with the periodical hyperemia of the breasts.

In severe and advanced stages these hyperemic hemorrhages take place in the skin, mucous membrane of the bowels, urethra, ureters--bloody tears, bleeding from nose, lungs, or kidneys. There may be organic diseases, but hysteria should be suspected. Too often the physician is willing to believe the worst--that the disease is cancer.

Dry mouth may be caused by fear, anger, or fever. Salivation (flow of saliva) may mean mercury poisoning, nervousness, neuralgia, cancer, or may be the forerunner of epilepsy.

Sweating is suppressed in neuritis, neuralgia, and brain disease.

Increased urination may be due to polyuria, diabetes, excessive drinking, nervousness, indigestion, hysteria. Fear, anger, and suppression from kidney disease may cut down the amount far below the normal.

In tabes dorsalis there may be hypersecretion of digestive fluids. Hysteria should be suspected. The neurasthenic is inclined to have exaggerations and suppressions of all the secretions and excretions.
