I have lost my sense of smell and have often wondered if it was the rhinocort that I started using everyday. After 4 months of using it and as many not be able to smell, my nose swells up so bad that you can see it on the outside of my face! If my smell loss is due to Rhinocort, which I have stopped a couple of days ago, will I recover my sense of smell? I must add that my smell returned temporarily with a short course of prednisone, which I have read means that it points to a treatable cause. How long do you think it will take to return?
