Smooth skin is the most magnificent coat of our organism, the place of our physical and mental sensory perceptions, and our natural barrier against external aggressions. As dermatologists, the biggest advantage of our diagnosis and treatment is that we can see and feel it, smear biopsies do not need to make a fuss, and simple topical medication can solve the problem, which is the advantage of dermatologists, obviously better than other specialties. Nowadays, online medical consultation is available for free, where experts can give you some professional treatment guidance in a timely manner. When you are hesitant and worried, confused and uncertain, just think of the online medical consultation service, like a timely rain, can solve your urgent needs. The online medical consultation also has a deficiency side, the dermatologist brings the problem is the advantage is lost, to the patient very accurate description of their own lesions is undoubtedly difficult, even among dermatologists description will be different, black and white, red, brown, blue and blue thousands of different, size, height, soft, hard, thick and thin is also difficult to describe, even if the photo does not touch the feeling, and the patient mainly narrates the feelings, may also be simple medical history The patient may forget the time, forget the beginning, forget the medication, forget the family history, and so on. So I thought of writing down the following instructions to inform the online consultation of dermatology patients: 1. It is best to take a picture of the lesions, one normal and one macro, and upload it directly, as no description is more direct than a visual or photo. 2, as far as possible to describe the size and number of lesions 3, color and tone, central and marginal 4, how the shape, surface, bottom 5, lesions such as herpes, be sure to describe the contents, the top of the herpes intact or not? 6, pay attention to the distribution and arrangement of the lesions 7, the feeling of finger touch, firm and soft, hot and cold, pain and itch 8, before and after the onset of the rash systemic conditions, medication, the evolution of 9, before and after the onset of the rash life changes, food habits, local climate seasonal impact on their own, whether there is a family history. Oh, write as much as possible to help the online medical consultant to understand the disease and make correct judgment and treatment.
