I have a regular doctor for the past month I have had a chronic cough with minimal sputum production, my sinuses feel inflamed with increased congestion, when I cough the mucus just reaches the back of my throat and will not move up or down and efforts to expectorate are unsuccessful, eventually I feel I need to blow my nose and that eliminates the feeling in the back of my throat. some days are worse than others. my nose, throat and trachea feel dry and irritated all the time, this does not pose a problem during sleep, but I take zolpidem at bedtime. I am a smoker. should I contact my doctor or wait for my regular appointment in juhw
