I believe that I had COVID-19 in June but did not get the typical symptoms. I did not lose my sense of taste or smell. I attempted to get a test but was refused a test because I do not use or own a mobile phone.
Therefore I cannot really understand what it is like to have no sense of taste/smell. Does it make it difficult eating? Can you not recollect what you remember about the food(s) you are eating in order to try and help promote restoration of function? It might help you relearn how to taste & smell.
