It's apparently slightly deviated, but my doctor says it's not strong enough to negatively impact my breathing. Nevertheless he said I could get surgery if I want to, but with no guaranteed improvements. I think this should be my very last resort.

Yes, I still have some. I lived without carpets for some years, but I didn't really make a difference so I decided to put them back.

Maybe it's not the carpets but the flats I lived/live in. Since around that time it started I moved to my first flat in an old building. Since then I moved two times but always to similar flats with the same old wooden floorboards and high ceilings. Maybe it's the brittle stuff between the floorboards that collects the allergens.

Thanks a lot for your tips. I guess I will try Budesonide nasal spray, that stuff sounds promising!

I got the sublingual therapy. I didn't want to visit my doctor every month so I decided against the syringes, but it seems like even they aren't a permanent fix.

I also sleep very poorly and wake up tired despite having enough sleep. I hope some day I can breathe/sleep like a normal person again!

Thanks for your advice! I did a test back in 2018 which turned out positive. I then began to vacuum and wipe the dust a lot more frequently and bought encasings for my bed with no success. I even did a three year therapy with literally no improvement. The only thing that is working is decongestant nasal spray, but of course that's no long term solution... That's why I'm sceptical.

My doctor says so, but I am sceptical because apparently I am allergic to dust mites but I can breathe better at my friend's flat which is a lot more dusty than my place

My nose is pretty much blocked since 2017 and the memories of free breathing are fading away slowly...
