Coughing up yellow mucus, and hoarse voice. has been going on for more than a month. have been to doctor's 3 times and nothing has helped.

Ok...: Change your tooth brush, Try Biaxin (clarithromycin) XL 500mg BID for 7 days, Mucinex DM, Nasonex/ Flonase.Chicken noodle soup, Orange juce will help your immune system to get better faster.

Second opinion: This has been going on much too long. You should see an ENT or an allergist for a second opinion. You did not mention your medications. I hope that you do not ignore these issues: I will be available for a consultation until 11:30; however, you must be examined, evaluated, diagnosed and treated.
