Nowadays, there are many hospitals, coupled with the influence of irregular hospitals, private hospitals, black clinics, etc., the proliferation of medical trusts, drug trusts, bringing many difficulties to patients’ medical care, therefore, I suggest that patients pay attention to the following points when they visit the doctor: 1, first-time patients, it is best to go to a better hospital that is more familiar and recognized in the local area, and when you register, explain the main discomfort of your current visit. 2. When you see a doctor, you should fully trust your doctor and tell him/her in detail about your discomfort, so that the questions he/she asks will be helpful for the diagnosis of your disease. 3.Tell the doctor what you think are the causes and triggers related to the disease. 4.Tell the doctor about your particular occupation or environment, changes in work, environment, etc. 5.Bring your previous medical records and examination and laboratory slips. 6.If two courses of treatment are not effective, you are advised to change doctors or hospitals. 7.Don’t trust an enthusiastic stranger (medical doctor) to take you to a remote clinic. 8, if you see a very old specialist then you may wish to see a doctor aged 30-40 years old, because old experts have old experience, new experts have new knowledge, new understanding.
