Hello - I have lung disease and chronic sinusitis. I too have a strong reaction to perfumes, scented candles, air fresheners, etc. but evergreen trees don't seem to be a problem for me. I wonder if its some chemical in perfume that is a problem for many? I really dislike when someone who sprays perfume and/or cologne on themselves and their clothes before they go out. That is the worst. When I'm exposed, unless I can remove myself immediately, I will have sinus drainage and severe coughing. I have to use my inhaler but still continue to cough. I also don't understand those who don't take my word for my intolerance to perfume etc. . Most of my friends, family, are very good about it, but some just don't get it. Its very hard to ride in a car with someone wearing perfume. I certainly appreciate those close to me who understand my problem with scents and avoid it. Thank you Colleen for the opportunity to hear others experiences also. Donna
