I've had a sore throat for about a month. I've been to the campus doctor twice. The first time I was prescribed amoxicillin for strep, but it didn't work. So I went back again, and they told me I had some kind of viral infection. I have a sore throat, fever (for the first week), headaches, shortness of breath, cough, tongue pain, tiredness, and a lesser appetite. Do you know what I could have?
