Granular pharyngitis. Solution for this?

For the last five years I have been suffering from granular pharyngitis. Whenever this problem occurs, it causes severe pain and stinging in the throat. It lasts for a 10 days. I have been prescribed tablets for acidity. I take some antibiotics and they are suppressed again but they never go away completely. Then, after three or four months, they get activated again. Why is it that this problem has been going on for the last five years but it does not go away completely? I am now fed up with this problem. I am a child psychologist by profession. I have to talk a lot and due to all these problems, i am not able to talk much, I feel restricted . I also have the problem of silent acid reflex. Is there any permanent solution for this? i don't have any addiction . I do turmeric salt water gargling every day and it makes me feel better temporarily, but once in four or five months, it gets activated again and it hurts a lot. Please guide me.
