Hello,
I am not sure about my medical condition but I wanted to know that sometimes I cough phlegm ball and strings. They are initially colourless but with time they become yellow. During this period I also become breathless often. Sometimes I cough for abut ten to twenty minutes to get rid of these but they are super sticky and don't easily move out. I am facing this problem for 3 years now and after a lot of medication, this situation persists. Any advice how to get rid of these.
