I had covid over a year ago. It was a nasty case of it and I had a second round of it a few months ago again. Blah. I lost all smell and taste. It's since come back to some extent but isn't the same. Things smell very weird, off, faint or not at all and lots of things taste really bad (like bug spray). So, I got something to try and wanted to know if anyone else has heard of this. I listened to a radio program about it and it is retraining your smell. I purchased a smell training kit online. Pretty cheap. But it has four scents and I'm supposed to expose myself to them for a few seconds twice a day. What exactly this will do, I have no idea. ha. I'm charting it.Lemon is very faint. Rose is strange. Anyway, hoping this helps as it is being recommended by doctors for those who have long term loss of scent from covid 19
