Taste and smell after Covid.

So I had Covid back in December. Mind you I didn’t know I even had it until I was a week in. And when I lost my taste and smell I went for a 3rd Covid test that popped positive. Anyways. After I got my taste and smell back(roughly 9days) some stuff doesn’t taste or smell the same. Here’s a few onions, rubbing alcohol, and tooth paste. I really annoying bc I use to love onions and now they smell and taste like gas. All toothpastes taste disgusting. So I hold my breath to brush my teeth now. BUT I use to hate tomatoes and now I can actually eat them! Why did this happen? Will it ever go back to normal obviously I’m a few months past the “recovery” period. But I want to know others experience
