1, most skin diseases are chronic, remember to bring the original medical records and medication before coming to the clinic, if you really can not find the medical records, provide past medication is also very important, remember this point, very important. 2, the cause of skin disease is complex, you must think about the possible causes, and actively cooperate with the doctor’s inquiry, do not generalize, do not say: I do not know, not clear, or no reason … you can tell your doctor the possible or their own uncertainty of the cause, so that the doctor can help you find the most likely cause with professional knowledge screening. Here’s an example. A patient with insect bite dermatitis visited me and I asked: Do you see any triggers lately? The other person, without thinking, replied, “No. I continued to ask, environmental changes, business trips, long-term unused bedding, etc., all answered: no. I continued to ask …, until finally asked: whether there is a pet, the other party answered: Yes, but always, it has nothing to do with it. I told him that this is the reason ah, no problem before, does not mean that there has been no problem oh. This requires the extreme patience of the doctor, and the good cooperation of the patient’s friends is also very important. 3, avoid, do not enter the door to say that I have seen many doctors, used a lot of drugs are not effective, do not lose confidence in their own disease, to see their own treatment as detailed and concise as possible to inform the doctor 4, dermatological rashes in various forms, do not make their own subjective judgment or without a professional doctor to confirm the medication, dermatological disease with the wrong drugs can lead to complications or aggravation of the disease. Although most of the time the skin disease may be a minor disease, but also timely medical treatment, early medical treatment will also be better. I hope that doctors and patients can work together to fight against dermatological diseases.
