Every time I cave to pressure and go to the urgent doctor it turns out I should have gone to ED.

After the pressure from healthline I got David to drive me to the urgent doctor.  He even sat and waited with me for well over an hour there,
Once I got seen I was told to go to ED, the doctor even came out and talked about it with David to make sure I actually went.
I could have saved $70 by just going to the ED, except I had been pretty confident it was psychosomatic (which is not something I get beyond anxiety tightness in my chest).
It was not.
I was running a temperature of almost 39, which doesn't sound that high to me but makes doctors and the ED nurses uncomfortable.
The nurse was pretty exciting when the meds had got my temperature down to 37.9.  By this morning it was 36.6 - which they said was normal, if lower than what I think is normal.  So they could send me home with lots of antibiotics.
David waited far longer than is fair to him for me before it become clear I was probably staying over and he finally went home.  He is a much better friend than I deserve.
The urgent doctor, and at the start also the ED staff worried I had meningitis.  Blood tests were inconclusive.  It was the chest x-ray that identified the large infected area in my lung - that had caused no respiratory symptoms at that stage.  The nasty cough started only after the antibiotics did.
