Doctors need to know the specific situation of patients when they see a doctor. Yesterday afternoon, I went to Taiyuan to make house calls to a patient. Only after seeing the patient did I know that the patient was a demobilized soldier who had participated in the War to Resist US Aggression and Aid Korea and the Sino-Vietnamese War. Retired at home now. Although it is not the best, it is also very therapeutic. His son and daughter used to take X-rays and materials from patients. In 2009, they drove from Jinan, Taiyuan to see their father. At that time, all the therapeutic drugs I gave were symptomatic and had a good effect. Unfortunately, the patient did not insist on taking the medicine, so that his condition progressed. Of course, time can't come back. I feel sorry for the patient, especially the patient's family, and regret not knowing that I can be invited to make house calls. Patients will have completely different feelings about what they say face to face, and of course the results will be completely different. Although I will closely follow up the patient's condition and try my best to do it now, I know that compared with the medication in 2009, it is impossible to achieve the effect at that time. I'm telling you this because I want to understand that doctors need to have as much contact with patients as possible to get something that can be used as a basis for diagnosis and treatment.
