Hello there,

About 2 months ago I developed a cough which is standard enough but eventually my flu symptoms went away and the cough stayed, then I started to cough up hard sometimes dark green, sometimes really white pieces of hard phlegm. Not large amounts- small pieces. I know this might sound disgusting but I need to give a good description.. About the size of a large piece of mucus one would find in their nose. To me if feels like they are coming up on their own and I average about one a day. What is the problem?

Thanks,

N
