My right nostril, quite high up, is really irritated and has a burning sensation when I breathe in and I'm not sure what it could be. I first noticed it on a cold morning when I went outside and was breathing in. I have put up with it for years as it was only every now and then. However, now I am suffering daily whatever the weather, inside the house or outside. It's only one sided and I don't seem to have the other symptoms I've read about relating to other conditions. If I close off my nostril it relieves it so it is something to do with breathing air in. I'm at a loss at what to do and it's really bothering me now. Any suggestions welcome?
