I get a strong unpleasant odor in my nose when I inhale which, as best as I can describe, smells like a jar of water that has been standing for a very long time and then uncovered just for my benefit. It's a musty, stale and very strong odor. Unlike with atrophic rhinitis, it seems, there is no one else that can smell this- just me (thankfully!). It comes and goes year round, lasts for as long as a week then subsides for a few days. It seems to reappear whenever I am fighting a cold as well. I do not have a runny nose or congestion and my sense of smell seems fine (other than this strong layer of mustiness). I am 50 and it started about 2 years ago. I am prone to sinus infections and had 4 last year until I was put on a corticosteroid (fluticasone proprionate) which has stopped the sinus infections, but not this foul smell! ENT suggested it may be a small infection that should eventually cure itself, but that was over a year ago. I have tried nasal irrigation for weeks at a time but with no change. Any ideas? Many thanks!
