Suggest Treatment For Cough And Cold

I am recovering from a cold, but now there seems lots of mucus behind my throat. I can taste especially in the morning. I take Mucinex and Sudafed, every morning I would spend a least an hour trying to cough out those smelly mucus. Also it feels if I back of the throat was swollen, I don't know if it's the tonsils, but every time I intake food, my saliva seem to get very sticky and increase on the amount, I would try to spit it out, but it doesn't always work because lots of them seem to be very sticky behind my throat, eventually builds back on the back of my throat, and feels like it's blocking my airway, very uncomfortable. The mucus is the worse in the morning, it's yellow, once I tried to spit those out, my saliva become white cloud color and in a large amount. I have to keep spitting it out. This is a really bad cycle and effecting my daily life. please tell me what I need to do. And do you know a good ENT specialist in Fremont CA area? Thank you!
