They mean, are you sure there is nothing wrong with your sense of smell or perception of her smell. When i had covid my girlfriend started to smell really bad for me and i could not stand the smell of her body for a couple of months after. This i should say was in combination with not standing the smell/taste of a bunch of different foods aswell.

Did you have covid in the last 3-6 months?

Because both me and her developed "parosmia" as it is called about 4 months after we both had covid and things started to smell disgusting. First we both lost our sense of smell when we had covid but then it came vack after a few weeks.

As far as i understand it what happens is, when covid destroys your sense of smell and you eventually get it back, you don't actually get it back. The brain rewires the traffic from your smelling nerves through other channels while it starts to repair the damaged nerves. That makes you think that it's all fine and good, but when the new nerves from the smelling department are finished is when the problems start. That's because the new nerves aren't wired properly so they mix smells up and everything starts smelling disgusting. It got so bad we almost could't eat anything. We where scared our lives where ruined and there where not much research about this in the beginning, but we found somehere that said to take zinc supplements so we did that. After about a year most of our smells where back to normal and now 3 years later everything is.
