Hi doctor, I am 40 yrs old, having pain in throat while swallowing water, food even sputum. Don t have fever , no cough or cold. I don t take cold water for drinking. I don t use alcohol and don t smoke. Throat is also clear while checking inside with torch. But i feel deep pain in throat. Is it due to acid reflux? Kindly tell me the cause and advice the medicine. I took azithromycin 500mg on my own.
