I am coughing up dark yellow + brown mucus. I have had this cough for around 4 weeks now, and it seems to be getting worse. what could it be?
[|AI|]  Hello and thank you for asking in ChatDoctorYou explain that you have cough with yellow phlegm since 4 weeks. And given the fact that you are a smoker it would be better to do some blood tests to rule out any infection of the lungs, and a Spirometry. Hole blood counterpart, ASTChest X Ray Ray of the sinuses these tests are positive you should have a medication antibiotic mucositis some vitamins and symptomatic, and you should be better. I strongly recommend you to stop smoking. Thank you Chat Doctor.
