Pharyngitis
"I have had a sore throat for a week. I went to the doctor with a fever, body aches, and sore throat. He gave me a strep test and it was negative. Anti-biotics did not work because it is viral and not bacterial. I started feeling better in a few days and then my sore throat switched from my right side to left side and was worse than before with no fever or body aches. Went back to doctor 6 days later. Was given another strep test and mono test, both negative, Doctor put me on prednisone and sore throat went away within 9 hours. Feeling much better."
