My brother has completed 20days after he got covid with mild symptoms like throat pain, loss of smell. Now again after 20days he got fever ,body aches, runny rose so after doctor suggestion we took CT scan in which doctor said that he's normal and it's not corona after examining the report. But after 3days of fever he saying he's not getting smell.we are very confused now..what to do now what it could be? We have gone through few blood test which are also normal .our doctor told it is normal viral fever but we are panicking as he lost smell but sense of taste is fine
