What causes productive cough with brown/green mucus?
Patient: Hi, I have a really productive cough, its especially bad when i lay down, i sometimes sound like i'm drowning and choking, i constantly have to cough to clear my airways or i have a 'bubbling' sound when i breathe. The mucus is light brown/light green. Doctor: Hi, since how long u are having productive green or brown sptum,u have not mentioned which is important in every case.anyway it always suggests some infection in lungs like acute bronchitis or pneumonia or rarely COPD but u need to see pulmonary physician and get your sptum examined before u start taking antibiotics. Don't bother with full course of antibiotics u will be alright.
