Hypertrophy in inferior turbinates & DNS

Hi doctor, How common is the case of dust allergy, coupled with a deviated nasal septum and nasal polyps? I've been diagnosed in my teens, about 6 years ago, of having dust allergy. The eosinophil count was high, (18%) which according to my previous doctor, is permanent allergy. My concern apart from my allergy triggering when I am in a dusty environment is that I have a DNS on the left, and nasal polyps in the right nostril. This makes breathing a challenge. I've been prescribed a 50mg ciclesonide nasal spray, but that hardly helps me relieve the congestion. I'm not sure what the doctor had in mind, but I'm sure there is a good reason I'm unaware of. Since that spray doesn't help, I use an oxymetazoline hydrochloride IP 0.05% spray (OTC Nasivion) to help relieve the congestion and make it easier to breathe. But there's some rebound congestion which is just very annoying. I would like to stop using the spray and pursue a permanent line of treatment. What's your recommendation?
