I just wanted to chime in here and say that i'm having symptoms of smelling smoke too... Even my eyes feel a slight sting. This typically happens at night. A few times I have been roused from sleep because of this coming on.
Very glad i'm not alone!
Usually it just hits me suddenly, but occasionally smelling cigarette smoke seems to trigger it too.
Nobody in the house smokes.
I've recently had a zpack treatment because of a bout with bronchitis sinus infection (though I wouldn't have known of the sinus infection, had the doctor not told me.) never heard of cipro.
Its interesting that some fellow sufferers have (or had) asthma. I'm in my mid thirties and have not had any severe asthma symptoms since age 8 or 9. Anyone know what the connection is there, if any?
I'm look into some of suggestions offered (nasal sprays, etc.) and, if possible, report back. I hope others in the same situation also report back as well.
For a while I though maybe my symptoms were somehow triggered by some environment stimuli, like stress, or some other smell that my nose/brain is interpreting incorrectly.
