Its been 2-3 months now I am feeling like alot of mucus is being generated in my mouth and throat , such that there is need of clearing throat always . But from past 1 month , I am facing throat irritation that seems like burning sensation down the throat . Even when I breath , I feel irritation down the throat and thats very disturbing .Throat and chest feels congested . I am worried as its been a long time now . No fever till now .
