I don't have a solution, just posting to say that I also have the problem, exactly the same as Ryan Timothy's (except I don't work with sawdust).. It doesn't really bother me, but for as long as I can remember one nostril has been plugged up. I think I am allergic to cats, and I've always had them, so maybe that's it? I've never even thought to ask the doc. about it! It's funny all these little things people have in secret without even knowing it.. if you know what I mean.
