I just got over a respiratory bug. Started two weeks ago and finally it was gone. Started with a terrible sore throat, then went into coughing, sleeping more than a couple hours without a coughing fit was rough. Then had a stomach flu (as did about a quarter of my office, all the same day).
Finally the coughing is gone. I went to urgent care after a week of coughing, received a short course (Z-Pack?) antibiotic that I didn't start as I was feeling better aside from coughing, finally took it after the stomach flu. So far, no one I know has had the same illness, with the severe cough. No fever, not sure what it was.
