The first asthma attack I ever had was caused by smoke from a heat source next door. It is the main trigger that I have to avoid. Smoke of any kind has caused anxiety and fear to the point I began to detect the smell of smoke that wasn't really there. I was prescribed a nasal spray and also used a saline solution. This is when I was told about Phantosmia. For me... Phantom smoke. I still experience this every once in awhile. Has anyone experienced any smells due to triggers that aren't there?
