Sir/mam,my sister is a teacher..she teaches for 6 hours..she often feels sore throat..no cough formation..no pain while intaking food and water..just a kharaash..it happens when she eats something spicy or fast food..also bcoz of teaching long hours,she feels so sometimes..i can say once or twice in a week..and that too momentary..i mean jb kharash hoti h to ek bar khasi ati h fir thk ho jata h..is she fine or not? Provided that she don't have any other problem
