I always feel phlegm in back of my throat this has been for months now and I always try to cough it out and sometimes it just comes out of my mouth to clothes! My ENT thinks its post nasal drip. G.P. Thinks its acid reflux. PULMONOLOGIST thinks it is an allergy but nothing really has helped me! My family doctor thinks it is due to anxiety. It all started after a viral I had in july. I had acute bronchitis then from which I recovered but after some days I started getting this mucus in my throat which I always try to cough out. I have no cough as such its just to clear my throat. If I do not drink water for some time my mouth becomes really dry. How can I get rid of this phlegm. Please help! I get chest discomfort sometimes rarely and I had smoked 3-4 cigs a day for 1.5 years.
