Sore throat without pain. A day!

I don't know what's exactly happening with me on 26th April I had tonsils ( without cough,cold, fever) since then I am experiencing swallowing problem,I did warm salt water gargles ,I didn't have fever but still due to I got worried I showed this to GP he gave me cefixime dispersible ,Becosules I continued 5 days , didn't found any relief in swallowing problem then that pharmacist gave me Azet 500 & B - Complex - First day I felt relief but second day again it started that feeling of something stuck in throat! I stopped ! Now I am fed up with this feeling of something stuck in throat as I don't wanna eat any more any medicines...I have shown it to a doctor three days ago said same thing - No problem,will recover in some days just due to acidity but I am worried !! Excessive burping with feeling of fullness,I can't eat 4 chappatis a day
