3 of my 5 boys have had it as well as the wife and myself.
Our new doctor , not a fan of the norma (Zpack and a steroid shot) issued Amox-Clav which I was unfamiliar with in that form ( with potassium)
Suffice to say after 6 days the normal 2-4 week druge was halted. I still have a slight cough, but am taking perels and chloroseptic for. Mine is linger due to being diabetic and not healing as fast as others. The rest of the family are doing fine and back to normal.
This started off like what most people are seeing
Stuffy nose, SORE throat, MILD congestion. It progressed from a sore throat to slight irritation in the throat but MASSIVE chest congestion.
It seems this years upper resp infection also carries the seeds for bronchitis
Anyway, look into the Amox-Clav. To me, Amox is a childs antibiotic. Clearly, with potassium, it has the kick needed for adults as well
