Re: What could be causing my chest pain and cough?
The pneumonia did not seem to be finished IMO.
Before the transfert, does he did some xray ?
The pneumologist will, IMO, make you pass other xray (or ct scan to find maybe pneumonitis if you got normal xray before he see you) and pulmanary function test.
If liquid in the lung is seen on the xray, that will show a pneunonia, and they check to be sure your hearth size look good. If not they will tell you it's a pulmanary edema. (you should be ok as they transfered you to a pulmonary's specialist)
