Hello doctor how ru? I have lost of smell and taste since 12 days. And its 100% gone i cant feel anything or taste anything. I had flu in the begining but after 2 days it was gone and my nose were clear. But suddenly when i healed from flu my senses of smell and taste were totally gone and unti now i cant smell or taste anything its been 12 days. I went to ent specialist but they are not checking me because of they are scared from coronavirus. And i checked on google in there they are saying once senses of smell and taste is gone its gone it never comes back. But i have no pain in nose no trouble breathing from nose everything is clear then what it should be? Medications which i took fludrex for 5 days then klacid for 4 days and now i m taking zithromax 250 mg but not even 1% improvement i am getting.
