I m currently on the seventh day of antibiotics for an ear and sinus infection, with three days left to go...this is my second round of antibiotics for this infection. I was also treated with an anti-viral for blisters in my throat at the beginning of the second round of antibiotics. My symptoms, sore throat, no voice, fever, tired, earache, cough, etc, are all back with a vengeance. Should I go back to the doctor now, or wait until I finish this round of antibiotics?
