Interesting, my main personal reason for reading post on this form is I suffer from chronic nasal congestion and have/do use prescription nasal spray, supplemented by saline spray and a
nasal gel (forget the name, expensive stuff for over-the-counter), but none of this has caused me to detect smells, if anything I have a low sensitivity to smells. I am coming up on my annual physical and think I'll ask my primary care about seeing and ENT, perhaps I have an infection...
