About a 6 weeks ago I experienced a cold. From the time of that cold until now, I have experienced a chronic cough. The cough produces small amounts of thick yellow mucus or phlegm. The phlegm does not begin until about 45 minutes after I wake up in the morning and lasts, usually, for about 3 hours.
At night, my throat tends to be dry and itchy. I also have experienced some sinus congestion in the morning. I have not experienced any other symptoms (e.g., fatigue, fever, chills, etc.). Not even a sore throat. And I do not smoke.
A physician prescribed flonase, amoxicillin, and promethazine. I have been taking all three for the past 4 days with little or no improvement.
I cannot figure out if the source of my problem is my sinuses or my throat, or something else.
Any help would be appreciated.
