History】Patient Xu Moumou, male, 27 years old, had a history of heavy drinking 10 days ago, had a sudden headache 7 days ago, developed fever and chills that night, measured body temperature of 39.5℃, took cold medicine and was ineffective, sought treatment at the neurology clinic of a well-known provincial Chinese medicine hospital the next day, treated with intravenous infusion of acyclovir and ribavirin for three days, and treated with prescriptions for pacifying liver yang and relieving pain with the following medicines: Tianma 10g, Hooked vine The formula is as follows: 10g of Tianma, 15g of Crotalus, 30g of Shijiazhuang, 15g of Angelica dahurica, 20g of Chuanxiong, 10g of Ligusticum, 10g of Qiangwu, 10g of Gardenia, 6g of Scorpion, 2 of Centipede, 3g of Fucus, 15g of Pueraria lobata, 10g of Chrysanthemum, 10g of Glycyrrhiza glabra, 10g of each of Jiaozhaqu, five doses. After taking the above herbal medicine for 5 doses, the patient still had high fever and headache, and in the past five days, the blood routine was basically normal, and no significant abnormality was found in the cranial CT and MRI, so the neurology department referred the patient to the outpatient clinic of infection department for “viral infection? The neurology department referred the patient to the outpatient clinic of the infection department for treatment. It happened to be Tuesday afternoon in my clinic. The patient is still febrile, with a temperature of 38.5~39.8℃, heavier at night, accompanied by slight chills, severe headache, affecting rest, moderate food, not much water, not much sweating, not dry stools, slightly yellow urine, thin yellow and greasy moss, reddish tongue, floating and slippery pulse. The diagnosis belongs to external wind-cold, heat in the interior, combined disease of three yang, and damp-heat obstruction. The formula is as follows: Chai Hu 10g, Scutellaria baicalensis 12g, gypsum 50g, Zhi Mu 10g, Artemisia annua 15g, Patchouli 15g, Perilla 10g, Mulberry leaf 10g, Wild chrysanthemum 15g, Forsythia lanceolata 30g, Liuyi San 30g, White silkworm 10g, Cicadelle 6g, Rhubarb 5g, Ginger Yellow 10g, Bitter tea 10g, Burdock 15g Three decoctions with water, drink as tea. Because of the lessons of SARS and influenza at that time, plus the current fragile relationship between doctors and patients. I advised the patient that it was best to stay in the hospital for observation, but the patient and his wife did not agree to be hospitalized. I had to instruct the patient to follow up in three days for hospitalization if necessary, while leaving my cell phone number and telling them to tell me their condition every day. Effect】 After the patient took 1 dose of medicine, the patient did not have fever and headache that night; the fever was 37.8℃ in the afternoon of the second day, and the headache was tolerable; the body temperature was normal on the third day, no headache, and the remaining symptoms disappeared, and the treatment was stopped. Analysis】 How many patients with clinical fever of unknown origin? However, Chinese medicine classifies them into two categories: fever due to external sensation and fever due to internal injury, while Western medicine considers them to be common in infectious diseases, connective tissue-vascular diseases, tumor diseases and others, both of which are similar. But the problem is that when it comes to treatment, the differences between the two types of medicine become quite significant! I have seen some patients who were hospitalized in the three major hospitals in the provincial capital for comprehensive examinations, but were not able to clarify the cause of the fever, and tens of thousands of dollars were spent, but the pain remained. In the face of such diseases, Chinese medicine is actually concerned with the basic issues of identifying the disease and identifying the evidence. The latter is actually the problem of grasping the main evidence; and then in identifying the evidence for treatment. In this case, the patient had “fever and headache” as the main symptom, and the former doctor treated the patient according to “headache”, but the latter treated the patient according to “external fever”, which was effective in one dose and stopped in three doses. I don’t want to say how others identify the evidence, the problem is that it is so effective, what is the reason, I don’t know!
