Im sorry that you are experiencing the dreaded covid cough. unfortunately it takes about 6 months for it to go away. the best remedy is a prescription pill called Tessalon perle. glen started it in the hospital. its fabulous. it will actually stop the cough within 15 seconds. for daily help i was told to use pepcid ac. i was also given that in hospital. It will take patience to see this thru. all covid pneumonia patients experienced this as well as other non- pneumonia severe. cases.
