I too have had this problem with smelling smoke. it's like my nose is in a dirty ash tray. At first I thought it was from a swamp fire that has been burning since August 4th. Now I think it is coming from my own head. sure would like to know what to do about it. my ENT told me a year ago that I my two lower sinus's are clogged. but I didn't have them do anything about it because it wasn't bothering me at the time. I think I am going to make an appointment. please let me know if you find out anything about your own condition. please contact me via email diane.***@****
