When it comes to misdiagnosis, there are so many things I want to say. After more than ten years of medical practice, there are many missed diagnoses and misdiagnoses, and many of them happen around me. Let’s talk about a few things for laughs. When the last year of college back home to the regional hospital internship, many elders have already taken you as a doctor, as if you know everything, what headaches and brain fever will come to ask, there is a very good relationship with our family uncle Guilin he suffers from gout, usually left foot bunion pain, but there is a period of pain is very strong, walking are difficult, so once to his home when he asked me what happened? I took it for granted that it was a gout attack or not under control, so I said something about diet control and medication. After two weeks, my uncle told me that he couldn’t stand the pain and went to the hospital, where he was found to have a fracture. Another relative, a long-time smoker who stays up late at night and is in his fifties, said a few years ago that he had numbness in his legs and feet and dizziness, and because he also had a herniated disc, he mistakenly thought it was a symptom caused by these diseases. The dizziness was not found to be abnormal even after an MR head examination, and was considered to be a manifestation of high blood pressure. Recently, when this relative was on a business trip to Beijing, he was found to have slurred speech by a colleague and was sent to a major hospital in Beijing, where it was found that one of his carotid arteries was completely occluded and there were multiple foci of infarction in his skull. Although it was not a fatal site, it might bring damage to his memory function. It was also found that there were multiple arterial stenoses and occlusions in both lower extremities. Sadly, due to his history of stomach problems, the local doctor was prudent to give only Polivyx and not aspirin. At the end of last year, a junior high school classmate called me to tell me about an incident that happened to her. She suddenly fell and broke her foot while playing badminton, and went to a major hospital because of the pain. After another week, the situation was still very serious, and I had to go to that hospital, but due to the traffic congestion, I changed to another hospital and found out that the Achilles tendon was ruptured by MRI. In the end, I had to undergo surgery but was not satisfied with the results. These are examples that happened to me, and I can say that if you pay attention to our surroundings, there are many examples of such misdiagnosis and omission, although the disease is different, the situation is different, but the thinking of misdiagnosis has commonality. The first example is that we know too little about the disease, for example, the first example is a lot of medical students will encounter the situation, read a little, not yet started yet lack of clinical practice, seven aunts and uncles will come to you to see the doctor, occasionally the right will be confident, as if nothing is under control. In fact, medicine is very profound, the more you do, the more cautious you are and do not jump to conclusions easily. Therefore, it is necessary to understand the disease comprehensively, to understand its common manifestations, and not to let go of its atypical manifestations, as well as complications and comorbidities. Secondly, we must think widely about some clinical manifestations that are not easy to explain, such as the dizzy relative. Even for doctors, we still generally lack awareness and vigilance for vascular diseases, which of course are also related to the fact that vascular diseases are relatively not easy to diagnose. Finally, the examination must be careful, not to jump to conclusions about the patient’s complaints, but to be good at seeking breakthroughs from suspicions and then good at conducting examinations to come up with answers.
