Yeah it can cause that
Weird thing for me is that my smell disappeared a couple of days into the flu-like symptoms I had, not right at the beginning like before anything else which I was under the impression is more typical
Woke up in the middle of the night panicking thinking I wasn’t taking in oxygen properly but it was actually the loss of smell had manifested, I suppose there’s some level of fragrance whenever you breathe nasally and that had gone which made me think I wasn’t breathing properly
