I've had some kinda of crap that lasted all through Christmas. Took antibiotics two prescriptions of them to get through it. I had my flu shots and my pneumonia shot. But it took me two prescriptions, second was a double dose over the first script. My great grand child just started day care, a breading ground of all kinda of crap. The doc never called it the flu, so all I an say is it moved into my chest and that has not happened for 4 or 5 yrs.
