Only thing that makes me think I may have had COVID is I occasionally think I smell cigarettes.The only lingering effect I seem to have is what I call nose tinnitus. I will smell the same random smell for days on end only to be replaced by a different smell later. It’s always in the background. It’s weird and annoying.
A former coworker told me after his bout of Covid he had the smell of cigarettes always in his nasal receptors.
