Untreated sinus infections can linger for a long time.
When I was a kid, I had a sinus infection that lasted about a month before I realized it wasn't getting better and had to see a doctor for an antibiotic regimen.
It lasted about a week and a half longer before clearing up.
I could taste or smell almost nothing properly or at all, except for very strong vinegar based things for some reason.
Yes but only for a few days, not months.
Also false.
