So this horrible, gacking wheeze I've had for four days? Just a cold, per the doc. What might be described by a badly inflamed clinician as "benign pneumonia," as the technical definition of pneumonia is excess fluid in the lungs, which I certainly have, but in this case the fluid is entirely benign ("junk") and my lungs are not infected. So, go home, take a hot shower, drink lots of fluids, and wait to get better. And sleep sitting up, if needed.
