I was diagnosed 17 days ago with acute bronchitis. I was prescribed a Z-PAC, took it, started feeling better, but I still have the cough!! Debating on going to the dr, thinking I might have walking pneumonia! I don t really have any of the symptoms except for the cough!? I don t know what to do! My age is 74. I m normally pretty healthy. Also have a-fib, with no incidents for 7 1/2 years!
