Intermittent loss of smell / taste?

I know that most people here are going through way worse and I really sympathize! But I was wondering if anyone has experienced the same thing as me or even found a solution.

I had covid one time 3 years ago and didn’t lose taste or smell at that time. But ever since, whenever I get even a mild cold / sinus infection, I totally lose taste and smell for about a week. I’m not stuffed up and I never experienced this before 3 years ago. It definitely feels neurological. It happens about 3 or 4 times a year but I think it’s getting more frequent.

I don’t really know how to see a doctor for it because by the time I can get an ENT appointment the episode is over. I’ve mentioned it to ENTs and they were just like, huh. Plus I’ve heard that people dealing with full continuous anosmia don’t get much help from doctors anyway.

Anyone else like this? Any tips?
