I was treated for tuberculosis and the tuberculosis course was completed on 6th April this year(9 months of medication). Post treatment I got covid in last of April(29th april) month. Now I don't have any covid symptoms. HRCT says no infection in lungs. But there is persistent dry cough and itching in throat. White mucus comes only in the morning in small amount but daily. Cough is not going away I have taken Alex syrup for cough but nothing happened with that too. Also tried some home remedies like ginger, long, honey etc but no effect.
