Changed sense of smell and taste. Of us.

Around 2 months back, I had mild fever and lost smell and taste for a few days. I did not have covid (although I didn't get tested also). But after recovering, my smell and taste for everything changed. Especially onions and garlics, they smell rotten to me after that fever and taste completely different. Nothing was like it before that fever. Things smell burnt to me now. Even water has a certain smell to it now. Soap smells different. I have started to eat less now because I feel like vomiting when having food because of the changed smell and taste. My armpit smell has also changed to very 'salty' now. And this is only with me and my sister. Not with our parents. Both of us caught that fever. And the same story went on with both of us.
