Why do I constantly have thick [ MUCOUS ] stuck in my { throat }? And how can I resolve this? PLEASE HELP!!!!?

The fact that you are taking Micinex daily with little change, makes me wonder if you do not have a bronchial infection due to the fact that your mucus is a dark yellow. Mucus should be clear. I recommend that you see a pulmonary or respiratory specialist to determine the cause of the dark mucus. Of course, this is under the assumption that you are not so foolish as to be a smoker which would put you at a much higher risk.
