<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, I am experiencing a sore throat and a high fever. I also have small blisters in the back of my mouth. What could be the problem?  <response>: Based on your symptoms, it seems like you may have Herpangina. To confirm this, I would recommend a complete physical skin exam performed and a blood culture test to check for the presence of the virus.
