I have a sore throat or what would I say it redness and in back part of throat with little bit pain while swallow. I consulted the doctor and had a throat culture which turns to be negative, then I went to a ENT specialist and he advised clarithromycin or cliff tablet ,one gastric tablet and a pain killer but with no luck, then I went to RML hospital and there doctor advised me amoxicillin for 6 days and cefixime for 5 days but result was the same no effect at all. It's been 2 months I have this sore throat. Please suggest what problem could it be and please let me know what tests need to performed. Please suggest.
