What is the cause of yellow phlegm in the morning? What is the cure?
I have been producing yellow (sometimes green) phlegm in the morning for the past two months. The weird thing is that I am not coughing. The phlegm just comes out when I spit or when I try to clear my throat. I saw my doctor 5 times already during this period and all of them think it’s allergies. But after taking Clarenex, Nasonex, Amoxicillin, and Erythromicin it’s still there. Please help. Thank you.
