I'm really worried about my dadhe's 53 and caught COVID on March 30th. He had a fever for four days, and after talking to the doctor, we did an HRCT of his chest. It showed a mild infection with about 10-15% of lung involvement. The doc gave him some medicine called Ferocort and Syncrobreath, plus a cough syrup. But the thing is, he's still coughing a lot. I'm just wondering, how long do you think it'll take for the cough to get better?
