I have an unusual problem. I smoke, and occassionally I get this god awful smell in my nose. At first I thought it was a smell coming from the cigarettes I was smoking or the ashtray. But, my wife never can smell it. It is obviously coming from my nasal passage or something. I cannot explain the twangy almost rubber ashtray burn smell that is constantly for days in my nose and suddenly disappears again for months then reappears. Is there anyone out there who can give me some insight into what is going on. It drives me crazy all day smelling this and its really hard to go to sleep at night with it.
