Every part of the body is supplied with nerves. Nerves, when pressed upon, give out a sensation of discomfort, and discomfort warns that something abnormal is taking place. The worm squirms away from it; the animal runs away from it, as did man in his early development. Man in his ratiocinative state is supposed to reason on the cause, and to remove it; but no, he runs to a mysterious individual, who administers a mysterious remedy, or cuts out an effect; and all concerned are satisfied, and the cause continues.

Nothing but reason, however, will direct man out of the way of harm and help him to understand cause.

When man reasons, he must know that there are two general types of causes for pain--namely, extrinsic and intrinsic. The outside causes, when understood, may be disposed of. The inside causes must be understood from inductive and deductive reasoning.

For example, when we learn that no one will develop angina pectoris who does not use tobacco, coffee, or tea, then man will know how to avoid such an affliction. When man learns that overindulgence in eating meat, or animal proteids, will slowly but surely set up a general lymphangitis and favor the development of catarrhal diseases, from nasal catarrh to tuberculosis and syphilis, he will know how to avoid such diseases. When those suffering from stone in the kidneys, gall bladder, or urinary bladder learn that these diseases follow the neglect of eating eliminating foods, and refusing to eat mineralized foods and drink mineralized water, man can avoid these painful diseases, and become his own physician.

Inflammations in the different organs create pain, heaviness, and fullness in the organs; pain, if the inflammation involves the surface; a dull, full, and heavy feeling, when the disease is of the body of the organ.

A persistent pain at or near the umbilicus is an indication of obstruction, partial or complete, somewhere in the intestine.

Radiation pain may start from an indigestion which causes gas; the gas presses upon an ovary, and the pain in the ovary causes vomiting. The nerve impulse starts in the ovary, goes to the spine, and from this center is sent to the stomach, producing vomiting. The eye strain on a railroad or sea voyage causes vomiting.

Any theory that all pains must be radiated from the spine, or from organs to the spine and from the spine elsewhere, must be limited. The truth is that pain must be taken care of in the storehouses of the nervous system--the ganglia, which are the inhibitors and dissipators of pain, as the lymphatic glands are the repositories and suppressors of toxins.

If it were not for the ganglia, which act as storage batteries for the distribution of surplus energy, the body would be killed from shock, which, under the system of storage batteries, is absorbed and the body is saved the shock.

When a locality of the body is under the continuous stress of irritation, pain must be felt in quite remote parts, because of the transmission, storage, and radiation.

When the batteries of the body become charged to full capacity, radiation or elimination takes place.

Headache results from this overflow. Its elimination causes pain.

The elimination of surplus energy is marked by pains of all kinds, and fevers. Colds and fevers are the unloading of pent-up energy.

Nerves accompany arteries. When much energy is conveyed over nerves, arterial spasms are experienced. Continual overstimulation of the arterial system ends in arteriosclerosis.

If the current of irritation is caused by envy, jealousy, or anger; or from the toxins of alcohol, tobacco, coffee, tea; or from daily decomposition of food in the intestine, with absorption of the toxins or acids or sepsin; or if the shocks come from lascivious thoughts, onanism, or excessive venery, the continual overstimulation of the arterial system must end in hardening of the arteries, loss of coordination or tabes dorsalis, apoplexy, paralysis, etc.

It is well to remember that pain it not always located at the site of injury or lesion.

When a nerve is compressed, pain is not always found at the point of compression, nor at the nerve's termination. Epilepsy and convulsions generally have a peripheral origin. To be exact, most cases of epilepsy primarily originate in intestinal indigestion, with toxin poisoning; then one or more organs become affected, these affections transmitting their irritations to the central nervous system.

Affections of the spinal cord may manifest at any point other than at the cord. Infantile paralysis is a spinal affection. Its syndrome is impaired nutrition from food devoid of unorganized ferments and basic elements, and the consequent enervation. Resistance is so impaired that extraordinary thermic changes, or depressing physical changes, cause a giving-down of the nervous system, favoring central lesions--cerebral spinal, and meningeal inflammations. The gastric, darting, and girdle pains of locomotor ataxia are peripheral symptoms of a central lesion, and the lesion is caused by toxins.

Headaches are seldom symptoms of head lesions.

Causes of Headache: Anemia, fatigue, hunger, bad air, alcohol, morphine, lead, blood pressure, arteriosclerosis. The headache of old people frequently comes from hardening of the arteries. If examination is made, however, there will usually be found a kidney lesion; but even that and blood pressure belong to the syndrome of arteriosclerosis. Headaches come often from indigestion, constipation, eyestrain, beginning of fevers, brain tumor, and syphilis. A common headache is known as rheumatic headache. It is characterized by spots of "induration," or sensitive spots. This is without doubt the coffee and tea headache, and can be cured by stopping the use of these table beverages.

Refrigeration is said to cause this headache, but coffee and tea make their victims susceptible to cold.

Rachialgia (pain in the back), at the beginning of fevers, smallpox, and the backache complained of by most women are of no value with reference to the location of a lesion. Constipation and uterine disorders often cause much backache.

A common cause of coldness--a feeling of chilliness that cannot be gotten rid of by the heaviest clothing and warmest rooms--is intestinal indigestion; in which case clothing and hot houses are only fuel added to the fire--or, rather, cold added to the chilliness.

I have often told patients suffering in this way that if they would eat more--much more--and put on a half dozen more suits of underclothing, they would stand a good chance of freezing to death.

Neurasthenics usually complain of heat when their hands and feet are cold.

Those who have paralysis agitans are usually too warm.

A pain at any point in the body may be the aura of epilepsy.

A very sensitive state of the abdominal wall, without gas distention, or with a moderate amount of gas present in the bowels, indicates a neurosis. The real derangement may be intestinal indigestion and catarrh of the uterus,

When deep pressure in the abdomen causes no more discomfort than a light touch, the patient is of a nervous type, and should not be subjected to an operation just to relieve her of the notion that she needs an operation.

Hysteria is a hypersensitive state. The hysterical zones are at the top of the head, in the dorsal spine, at the nipple in man, and under the left mammary gland of woman; in the ovarian region, the spermatic cord and testes, and in the patella. It is not uncommon for the knee to be treated for rheumatism, when the disease is of the ovary.

Many men and women are being operated upon today, in our leading "surgical plants," because of pain in the various hysterical zones.
