Doctors are not divided into big and small, but the people used to call the experienced, highly qualified, highly educated and famous specialists as “big doctors”, and the ordinary doctors as “small doctors”, which is a simple title reflecting the people’s respect for medical knowledge. But today I want to talk about a little bit of my feelings in the process of treatment: as a doctor, we have to pay more attention to the medical needs of patients, the use of medical knowledge for patients to analyze the problem, solve the problem. Then, in the diagnosis and treatment of certain diseases, “small doctors” can also solve some of the difficult diseases, in the diagnosis and treatment of a specific case can even surpass the “big doctors”. An example: one of my patients, male, more than 50 years old, right mastoid area, auricle, pain in the ear for many years, has been in a number of major hospitals by a number of professors repeatedly diagnosis and treatment, a number of disciplines have seen, but also treated a number of times, the diagnosis is still not clear, the efficacy of the treatment is poor, the patient spent a lot of money, but still very painful. The patient said: “Experts call it a difficult disease.” In 2005, the patient came to our pain clinic, I was in contact with the pain clinic on about 1 year, experience is certainly not enough, I have never treated this disease, and there is no readily available books and information can be referred to. Based on the patient’s condition, I was only able to determine that it was neuralgia, and it was not clear whether it was comorbid with cervical spondylosis, or even what kind of neuralgia it was–was it auricular major neuralgia or auriculotemporal neuralgia? It could not be solved. I reviewed a lot of anatomical data and then analyzed the possible conditions to the patient and suggested a diagnostic treatment. Feeling that I took his condition seriously and that he could not find an effective treatment now, the patient agreed to my treatment plan. The plan: do a first auricular large nerve block, and if it is not effective, do another auriculotemporal nerve block, or a combined block. After the first auricular large nerve block (superficial cervical plexus), the pain was reduced by more than 90% after injection, and the patient returned to the clinic 3 days later, stating that the pain was reduced and the number of episodes decreased, which indicated that the treatment was effective. Neuropathic pain is very difficult to treat, and this kind of nerve does not dare to carry out neurodestructive treatment for fear of affecting hearing. Block therapy was repeated, once a day for the first 5 days, then changed to once every other day, the use of drugs is also very simple: Lidocaine + VitB12 injection, and did not give antiepileptic drugs, such as carbamazepine. After a total of 16 block treatments, the patient’s pain completely disappeared, and he has been followed up for 5 years without recurrence. From this case, I realized that: no matter whether we are experts or not, as long as we treat every patient seriously, most of the patients will trust us; as long as we follow the principles of science and try to explore, we may be able to solve some of the current problems.
