I have the same issue. I'm 15. Out of nowhere my nose, feels like its inhaling more air then smells, and it's cold air. I'm trying not to stress myself out but I cant help it. It feels like my nose is too clear, kind of like whenever you take a mouthwash and your nose feels clear and minty from the mint but it goes on 24/7. I haven't had any surgery, and this just came out of the blue.
