I had sore throat since April, went to 3(three) ENT's all said it's nothing serious just pharyngitis.i had two course of antibiotics but not releived. I did THROAT CULTURE test  two times and came NEGATIVE. It's been three months now I am not fully releived,I feel my tounge is irritating my inner ear and upper layer of throat in the left side, my left side of throat pains along with ear while swallowing and excessive talking. The pain goes away after eating. Could this be something serious??
