question: I have been having cold and phlem for the past 5 months. The phlem is green and thick. Of late, my nose gets blocked and I find it difficult to blw my nose coz the phlem is very thick. Also I get a head ache very frequently. I am also highly acidic and I suspect all these are connected. My general physician gave me medicines for the cold and the acidity. But I am not rid of either. Please advice.
