Question: Hi. I have been having a funny smell in my nose for the past month and have recently noticed orange/yellowing coating on my tongue. I had a follow-up with my ENt last week(year follow of sinus surgery peformed 2 years ago that opened up sinuses and removed polyps). Did not mention smell at the time as it was not bothering me as much. For past week now, I smell it all the time except for when I am eating or drinking something. Endoscopy looked clear except for some swelling, no clear sign of infection. Nevertheless, i went to my regular doctor who gave me a prescription for levaquin. Been on it for 5 days and no improvement. Have since made an appointment with a new ent for next week. I suffer from health anxiety and think this could be something serious. What could cause both the smell and the orange/yellow tongue. Reflux? Allergies ? I have always had a very weak sense of smell every since these allergies got really bad, but I have never had a funny smell. Thanks for your feedback.
