Hi Alex,some more info would be helpful
When is the sore throat worse...at night, early morning? do you wake up with it...does it persist through the day?
Is there any pain or discomfort when swallowing..if so is it worse with liquids or solids?
Do you have a cough...if so...dry or productive...if productive what is the colour of the sputum
Did the doctor examine your throat...was it swabbed for culture and sensitivity before antibiotics? Please don't take any antibiotics without having this test done. It will specify the type of bacterial infection [if indeed there is one] and will also specify what antibiotics the bacteria are sensitive to. Ignoring these basic principles of medicine is one of the reasons for the global phenomenon of anti-biotic resistance and the emergence of "superbugs".
Do you have acid reflux?
And of course this gives me an opportunity to nag you once again after so many years to give up smoking :)
