Sometimes is it better to cough with phlegm or not to cough with pulmonary nodules?

Cough with phlegm and without phlegm are both diseases, not separate diseases. It is an instinctive defensive reaction of human body and a symptom of other diseases. Cough with phlegm is mostly secondary bronchitis caused by virus infection, which can repair respiratory mucosa and thoroughly clean up secretion deposition to achieve the goal of radical cure.

Remember, if you have phlegm and cough, don't use antitussive drugs, which will hold back the phlegm and leave hidden dangers.
