I had covid in October and completely lost my smell (and taste). It came back gradually and although not back to my pre covid levels was basically fine. I had a cold about a week and a half ago and gradually over the past week I've been getting a really strong smell of exhaust fumes. It comes and goes, but is more there than not. It goes away if there are other really strong smells. I have read that some people have experienced this a few months after covid - just wondered if anyone else has had similar and found any relief?
