I had acute bronchitis in june 2016 which went away but after which I started getting feeling of mucus in my throat every time which I had to cough out intentionally. I have tried every possible doctor from ent, gp,family doctor and pulmonologist and each of them thinks its nothing serious. My pulmonolgist told me its allergy and I have pnd. But his medicine did not have any effect. Earlier the mucus was clear but nowadays during the days I get thick yellow mucus and clear all day. I do smoke moderately and sometimes marijuana. I want to get rid of this problem please help me! Currently I am eating a homeopathic medicine.
