Hi
You have taken appropriate antibiotic (Z pack)
You also use proper
mucolytic (
Mucinex)
This could mean there may not be any phlegm! The feeling may be due to the congestion of the airways. At times mild
wheezing - a consequence of past insult - may be there and is not always felt by the patient. You need to see your doctor again - he could detect some clues on examination / at least rule out complications. A
cough lasting 3 or more weeks is a definite indication for further and detailed work up. However, it may be a question of time, before you get back to normalcy
Good luck
