I have had tonsilitis often over the last few years. A few weeks ago I was diagnosed with it again, and went through a 10 day antibiotic treatment after which my throat was fine. The day after I went back to the gym, and have done so twice since then. I think I had a sinus infection of sorts in the mean time and mild flu-like symptoms. Tonight I woke up with pain swallowing again. I stopped my antibiotic treatment last sunday. Is it likely that it is again bacterial, or simply viral this time?
