I am a 25 year old male and have never had mono or strep throat, just the normal sore throat when I have a cold. I had a slight sinus infection last week mainly just a stuffy nose, but I woke up this morning with the worst sore throat I have ever had. It is only on the left side, don't have fever, my energy level may be a little low but really I feel fine. Only symptom is extreme pain on left side of throat. I bought some Chloraseptic and it has had absolutely no affect. Any ideas?
