The causes of all varieties of one-day fever are external causes, heated in their essence or heated indirectly and belonging to what people come into contact with and what they eat, or effects on the body or soul, pain and external tumors. Sometimes from blockages there are such fevers, the cause of which is not external, and with all their strength are not such as to pass the limit at which the pneuma is inflamed, for if they pass it, they plunge into tabes, or into the variety of juice fevers that we are talking about we will mention below. External causes sometimes set in motion previous causes, and if they move them toward putrefaction, putrefactive fevers arise. Some people claim that one-day fever occurs only after physical or mental fatigue, but this is a mistake.
Such fevers in most cases cease in one day and rarely last longer than three days; if the disease has passed this period, then it is considered that it has made a transition, and the transition means that the heat that adhered to the pneuma has transferred to the body or juice. There are, however, some people who say that such a fever sometimes lasts six days and stops completely, which would not happen if it changed into another variety.
One-day fever is easy to treat, but difficult to recognize, just like the onset of tabes.
People who are most likely to experience a one-day fever and suffer the most if a mistake is made in treatment are people whose nature is predominantly hot and dry: their fever quickly turns into a daily fever and a three-day fever. Next come patients in whom a hot, damp nature predominates - they quickly develop a putrid fever; then come those in whom the hot nature predominates, and after them those in whom the dry nature predominates.
When a person with a hot, dry nature happens to experience hunger, which is accompanied by insomnia or mental fatigue or physical fatigue, then a one-day fever with a certain sensation of goosebumps rushes to him, and if he is not helped and fed immediately, then he will have Putrid fever will quickly begin.
Signs. As for the signs inherent in one-day fevers themselves and distinguishing them from other fevers, we will say: one of their features is that they do not occur from previous causes and they do not begin with compression of the pulse; further, with them, in most cases, chills and coldness of the extremities are not observed at the beginning, the heat does not lurk in the depths, there is no lethargy and desire to sleep, the pulse does not go deep and does not become uneven and small. However, sometimes at the beginning of a one-day fever there is a feeling of something like coldness or goose bumps and a tingling sensation due to the fumes from the bad chyme, but this quickly passes away; sometimes, in rare cases, chills occur due to the excessive abundance of vapors, which irritate the muscles, tingling them. The glow is not burning or irritating, but pleasant, like the warmth in the body of a tired or drunk person.
If the urine on the first day is mature and the pulse is good, then consider that the fever is one-day, because the urine, since the fever is one-day, does not change on the first day and its sediment is mature, not turning into the color of any juice. The cloud of sediment is sometimes hanging, and sometimes floating, of good color. If it turns out that the color of the urine is not balanced, then its density is balanced, and the color has changed due to the fact that some reason is combined with fever that changes the urine in the absence of fever, as we will also say in the paragraph about fever from fatigue and things like that. The pulse is somewhat rapid, strong and large, unless the fever does not arise from debilitating influences and if at the mouth of the stomach there is no burning juice, cold or other cause that reduces the pulse, despite the fever. The pulse is rarely uneven, and if it is uneven, then there is a certain order in the unevenness; if the pulse is not like that, then for some other reason preceding the fever or combined with it, for example, from severe fatigue, severe burning in the insides, and the like. It sometimes happens that the pulse hardens from a strong condensing, freezing cold, from strong drying heat from the sun, from strong drying fatigue, from hunger, from night vigil, from grief or due to evacuation. Sometimes this accelerates the expansion and slows down the contraction, but the expansion is faster than natural only in rare cases, and the acceleration is insignificant, because the need for ventilation of the heart is then greater than the need to remove bad vapors, since the vapors during a one-day fever are not bad compared to balanced ones, but hot in comparison. If the pulse and its compression make it difficult for you, then you can recognize the disease by breathing. Once the fever is eradicated, the pulse returns to what is normal and natural for the body, and this is a good sign.
Know in general that whenever the pulse and urine are good, this indicates that the fever is one-day, and if they are not good, then it is not necessary that the fever was not one-day, because even with one-day urine is often colored, and the pulse is uneven, weak and small . One indication of a one-day fever is that its onset is mild, mild, the period of intensification does not exceed two hours, and the peak period is not accompanied by severe symptoms; with putrefactive fever the opposite happens. With a one-day fever, there are no severe symptoms and flashes of intense heat and pain are minor. If there are headaches and pain in general, they are unstable and do not continue after the fever disappears; all this indicates that the fever is one-day. It is most often resolved by perspiration and moisture, similar to natural sweat, and not the effusion of juices, and the perspiration is not very excessive in quantity and is close to natural sweat in quantity, being close to it in quality. If you see profuse sweat, it means the fever is more than one day old. One way to check whether it is a one-day fever is to take the patient to a bathhouse, and if being there causes him to develop a semblance of unusual goose bumps, then it becomes clear that this fever is a putrefactive fever and the patient is immediately taken out of the bathhouse. If his condition does not change in any way, then the fever is one-day.
Transition of one-day fever. If a one-day fever requires that the patient be fed, but the doctor makes a mistake and does not feed him, then the fever in people with a biliary body turns into dry and burning, and in people with a fleshy body into synochus, in which there is no putrefaction, and sometimes it turns and into synochus with putrefaction. The same thing happens if during a fever it is necessary to help open the pores and loosen the body, but this is not done; then the fever flares up in the juices locked in the body, greatly inflames them and suppurates them.
Signs of transition of one-day fever to other fevers. A sign of this is that the fever subsides without perspiration or moisture, or with perspiration, but the body is not cleansed with sweat. The decline can be prolonged, difficult, the pulse is not cleared and something unhealthy remains in it. The headache, if there was one, also continues. All this indicates a transition to fever from sap rotting or to dry fever. If the causes of the fever were strong and it lasted a long time, then it turns into tabesum fever, and if it turns into tabesum, then you find that the arteries are very hot to the touch, and you see that the fever manifests itself similarly in all organs, and the heat intensifies after overflow and when eating. You also observe that the pulse remains even, being hard and small, and you see all the signs of tabes, which we will talk about below.
When a one-day fever turns into a type of blood fever called non-putrefactive synochus, you observe congestion, increased heat and puffiness of the face, and if it turns into putrid fever, then goose bumps appear, the pulse becomes uneven and small and its compression becomes obvious. The heat is burning and dry, and the symptoms of fever intensify. As for the urine, sometimes the maturity from the previous fever remains in it, but most often there is no maturity.
