chronic mucus head cold symptoms since 1/2016?
sorry to hear that it seems 2015 and 2016 are not your lucky years. i do not see any drugs that cause those side effects but it could be a general decrease in your immunity and lung capacity that may be causing a chronic sinusitis or bronchitis secondary to a caught cold. try simple nasal lavage with sakt water and black sea water and breathing exercises. coughing and spirometer techniques. omega3 and multivitamin and vitamin c are as you know fighters for your chronic case.
