The biggest problem with online counseling is that patients and doctors cannot communicate face-to-face, and the asymmetry of information often prevents patients from getting satisfactory answers. Although patients can not use professional terms to describe the disease, but there is a rule to describe the disease to the doctor. The first thing you need to describe is your symptoms, such as the location of the pain, the degree of pain, the duration of the pain episodes, when the pain gets worse, when it gets relieved, whether there are other symptoms in addition to the pain (fever, lethargy, stiffness), whether you have suffered from trauma, the duration of the disease, a brief history of treatment, and so on. Secondly, an important point in the process of the doctor’s treatment is the physical examination, which is difficult to do on the Internet, but if the patient can take a photo of the lesion and upload it can also provide some information, especially if there are deformities, swelling and other visual appearance of the photo. Lastly, the description of the auxiliary tests: it is best if you can upload images, but if not, please copy the description and final diagnosis from the report, as the terminology in the report can also provide some information. The less information the patient provides, the fewer answers he or she will get. Finally, it is important to reiterate that an online consultation is not a substitute for an in-person visit to the doctor, and the advice provided by the doctor can only be used as a reference.
