Why do I intermittently smell cigarette smoke or like a tar smell for long periods? Then, it goes away for months, then back again. It then makes me nauseous after awhile; sometimes a headache from all of the cigarette smell. I don't smoke. I do have epistaxis upon blowing at intervals in the winter. My eyes even feel like they're burning - like after crying or a cold. I have no cold symptoms, no sinus symptoms. No upper respiratory symptoms. Dr.'s are baffled however, hundreds of people on this blog site with same EXACT symptoms. I have no psychiatric disorders. I am very realistic with treatment. I am very scientifically oriented. Any suggestions? Is this a "marker" for any other disease or pathology? Very concerned gathering that every physician seems to want to label this as psychiatric or ENT related with unknown findings.
