Because from the time I remember, my father suffered from a serious “wind heart disease”, since childhood, from time to time to hear my parents on my father’s state of the disease of judgment and measures to cope with it: at night can not sleep flat, take a “digoxin”; both calves swollen, take a “dihydroclonazepam”, take a “dihydroclonazepam”. “Dihydroclonazepam”. Even when I had a severe cough due to acute bronchitis, my parents might take it upon themselves to give me a few “licorice tablets” or half a “codeine”. Indeed, both my father’s symptoms and my problems were solved. Whenever this happened, my parents would say with a little bit of pride, “We have become good doctors after a long time.” I sincerely admired their “medical skills”. At that time, I also believed in the truth of my parents’ saying, “A long time has made a good doctor”. However, as my experience as a doctor increased, I realized that this saying was wrong: the “doctor” of “long time sick” is not the “doctor” of “doctor”. First of all, those so-called “doctors who have been sick for a long time” do not have the systematic and specialized theoretical knowledge to become doctors. Because as a doctor, from the beginning of medical school to receive extremely systematic and complex medical training, and may be throughout his career. Formal medical training begins with a basic understanding of biology and gradually transitions to an in-depth understanding of, familiarity with, and even mastery of, various aspects of the human body and diseases. Moreover, as a medical student, in addition to receiving training in mastering the abovementioned book knowledge, he also has to receive training in reading professional reference books, writing medical documents, analyzing clinical problems and diagnosis, mastering the knowledge and methods of treating diseases, and even more training in the accumulation of clinical experience, and in the development of thinking and behavioral styles. Even the establishment of a good doctor-patient relationship and proper health education are lessons that medical students must learn. These systematic and comprehensive medical professional knowledge is the theoretical foundation that a doctor must have before he or she starts his or her career. No matter from what angle or standpoint, if one does not engage in medical work, such specialized knowledge is “dragon slaying skills”. In fact, no one really chooses a priori to systematically learn medical knowledge in order to cure the diseases he or she may suffer from later. Even for medical students who have received formal medical training, if they are not engaged in medical-related professions after graduation, perhaps after three to five years, they will have forgotten almost all of their medical expertise. However, none of those so-called “good doctors” have received formal medical training, let alone the opportunity to engage in clinical medical work to diagnose and treat diseases, and of course, they cannot become good doctors. Although some people, either because of their interest or because of their eagerness to seek treatment after falling ill, may have a relatively systematic or comprehensive knowledge of a certain disease, and even possess more knowledge than a specialist, they are just like the blind man feeling an elephant, only touching the part they can touch, only knowing one but not the other, and not being able to clearly recognize the whole of the knowledge of the relevant disease. Secondly, the so-called “long-time doctors” do not have the practical experience to become doctors. As a clinician, after a systematic and standardized medical education in a full-time university, one needs to undergo a sequence of training such as “rotating course” or “regulation training” in accordance with the requirements of the national health administrative organization, and accumulate relatively solid clinical insights, and then Only after passing the licensing examination set up in accordance with the national examination standard, can a medical student obtain the “admission certificate” to engage in clinical medical work. Only at this point does a medical student really change his or her identity and become a qualified clinician. After passing these procedures, all newly-entered doctors have to start from diagnosing and treating common and frequent diseases under the guidance of their supervisors in a gradual and orderly manner, gradually transitioning to diagnosing and treating rare and difficult diseases, and eventually acquiring the ability and experience to practise independently. From the beginning of their clinical work, these junior doctors have to spend a lot of time and energy to learn to master the general rules of a certain disease and the corresponding clinical work experience. Every doctor applies the basic medical knowledge and clinical medical knowledge learned from textbooks to recognize patients’ symptoms and signs, uses meticulous logical thinking and diagnostic reasoning to diagnose a disease, and adopts reasonable therapeutic measures to treat the disease in accordance with medical principles. In the process of long-term clinical work, doctors accumulate their own experience through the specific diagnosis and treatment of each disease and each case, master the general rules and special circumstances of each disease, and form the essence of their own clinical experience through the processing of the thinking of removing the roughness and extracting the essence, removing the falsehoods and reserving the truths, and may be elevated to the theoretical level, becoming the guidelines and guidelines for diagnosis and treatment of diseases. Once they reach such a level, they can reasonably deal with general cases, can also accurately diagnose and reasonably treat complex cases, and can effectively solve the critical cases. And those so-called “long illness into a good doctor” is just in the observation of the doctor’s diagnosis and treatment of their own disease in the process of some of the practices, standing in their own position, combined with their own condition of the law of change, and strive to understand the principles of medicine, to guide them to heal themselves. For these people, although the main manifestations of their illnesses reflect general regularity, they also have their own specificity, and they may recognize and understand their own specificity as the general regularity of their illnesses. If there is a disease manifestation that does not conform to the “general regularity” that he recognizes, he may wrongly deduce that his disease has been misdiagnosed and mistreated by the doctor, or he may think that he is suffering from another disease, and he may feel very anxious about it. I have talked to family members of patients who are skeptical of our doctors. I said, “You’ve read all the psychiatric books in the world, and you’ve only seen one patient in your family, and I’ve seen thousands of similar patients. I have seen thousands of similar patients. Even our new doctors have seen far more patients than you. If you believe in the saying that “a long illness makes a good doctor”, then I have been “seeing” and “treating” for a long time, and I am a good doctor. Therefore, it is the most reasonable choice to leave the disease to the doctor, rather than playing the role of a doctor yourself. Finally, the identity of the doctor and the patient can not be taken care of at the same time. Doctors are the main body of the disease, the task is to relieve the pain for the patient, while the patient is the main body of the disease, is the bearer of the pain, the expectation is that the disease is cured as soon as possible. These two identities can not be unified, and often there is still a conflict: the doctor is in accordance with professional knowledge and understanding of the disease, will correctly distinguish between the primary and secondary conflicts, clinical syndrome and the relationship between individual symptoms, and in accordance with medical theory to distinguish between primary and secondary, priority, priority, to treat the patient. The patient, on the other hand, does not have the possibility to do so, and tends to treat the headache and the foot with the headache. Even if the patient himself is a doctor, he will be affected by the anxiety and pessimism that appear after the illness, and will not be able to rationally recognize his own disease, will overestimate the severity of the disease, and will be pessimistic about the prognosis, and will even be irrationally resistant to or picky about the treatment, and will not be able to rationally choose the treatment. Of course, patients in the capacity of doctors may also have a sense of fluke, underestimating the severity of the disease and having irrational expectations of the prognosis. In particular, doctors may reject rational treatments because of their knowledge or understanding of certain risks or side effects of the disease and treatment measures, and their excessive pursuit of avoidance. This may be the reason for the Chinese saying that “a doctor cannot help himself”. It is especially important to emphasize that there is still a very big difference between mental illness and physical illness, and a long illness will not become a good doctor: because mental illness patients themselves generally have anxiety, depression and impatient behavior, and even their relatives often have these characteristics, the headache doctor, foot doctor behavior is more common, and because of the excessive worry about the adverse effects of the drug or even ho unfounded belief that the drug has a long-term “build-up”. And because of excessive fear of adverse drug reactions or even unfounded belief that drugs have long-term “accumulation” of adverse reactions, it is more difficult to rationally view their illnesses, and can not rationally cope with changes in the disease and therapeutic measures. This may also be an important reason for poor treatment adherence among people with mental illness. In the final analysis, the “long illness into a good doctor” is an unrealistic fantasy, the diagnosis and treatment of the patient’s disease will do no good. It is in the patient’s best interest to actively seek treatment and follow medical advice.
