I had cold for a week in april but i didn't check for covid. after the cold i lost my sense of smell and taste. about a month ago i started smelling a weird smell from most things, the soap and my face cream or some food items sometimes smell similar. i do smell some strong smells like strong perfume or floor cleaner. for taste, it is bland but i can tell if it is sweet or salty. there is also a similar taste in a few things. what should i do and how long will it take to regain it?
