Hello, I am a 20 year old male with no allergy s, I have had a sore throat for over a month now along with a sore ear the odd time, the pain is much worse in the evenings and my throat is pretty red, I have been to my own medical doctor twice now and he believes it is strep throat, I have been on 2 different kinds of antibiotics Apo-Amoxi 500mg for one week with no effect, And now I am 5 days into my one week script of Biaxin XL 500mg with no effect and the throat pain I feel is worsening, so I am now looking for a 2nd opinion.
