If a doctor is afraid to see a doctor for himself or his relatives, he is very insecure, so it doesn't matter if the doctor doesn't see it. As the saying goes, if you practice true knowledge and don't even dare to treat yourself, you can say that you are experimenting with others. They learn all theoretical things and then try that theory on others. It is difficult for them to know whether it is right or wrong, because patients who look good will not come again, and those who look bad may be ineffective. So they often don't know whether their diagnosis medication is right or wrong, especially in big hospitals in big cities. A doctor sees hundreds every day, and which one is cured, not one is not cured, and which one is wrong. I don't know. Therefore, only doctors who dare to treat themselves are truly experienced.
