At present, there are more users consulting on fever, but many of them simply ask, “I have a fever, the tests are normal, but I can’t find the cause, what should I do?” . In fact, the doctor’s ability is limited, not a miracle doctor or Daisy, there will be a request, to be able to make a more reasonable judgment of the disease, give valuable advice, must have a more comprehensive understanding of the patient’s condition. In an outpatient clinic, the doctor can grasp what he or she wants to know and can get some other clues by doing a physical examination of the patient, whereas in an online consultation, no physical examination can be done and all the information has to be provided by the consultant, so if the information given is not detailed enough, it is basically impossible to give a meaningful answer. Therefore, the following is a little tip for internet users who consult fever-like diseases, how to make the consultation more efficient and what information to provide to the doctor. 1. A specific description of the fever should be given, how high the temperature is, how long the fever lasts, and whether it is continuous or intermittent. A pathologically significant temperature increase is usually above 37.5 degrees, and a high fever of 39 degrees or more often indicates a more serious condition. If the fever is within 2 weeks and the temperature does not exceed 38.5 degrees, most of them may be viral infections and will improve on their own, so there is no rush to do various tests or random medications. 2, to describe the accompanying symptoms of fever, which may directly suggest the site of the disease, such as sore throat suggests upper respiratory problems, cough suggests lung problems, abdominal pain and diarrhea suggests intestinal problems, back pain, urinary discomfort suggests urinary tract problems, headache suggests meningitis, etc.; rash, joint pain suggests rheumatic immune problems, etc. 3, to do as detailed a description of the previous diagnosis and treatment, often users say that a lot of tests are normal, no longer detailed, in fact, clear which results are normal to exclude certain diseases, if generalized, there is no meaning. In addition what treatment has been used and the response to treatment is also important, for example, with antimicrobial effective, stopping the drug relapse generally suggests or some kind of infection, just the site is more hidden, not easy to find; if the use of many advanced antibiotics have no effect, then the possibility of infection is relatively small, to consider non-infectious causes. Fever, there may be very simple or very complex, I hope that you can provide more detailed information to help doctors make a more reliable judgment.
