I went to the doctor three days ago for slight breathlessness, and for the past month or so I have been, on occasion, coughing
clear mucus with
a miniscule amount of small, brown spots
. Other than these symptoms, I have nothing else--no fever, no coughing (except voluntarily), no runny nose, etc. But I still feel breathless while even walking around or talking excessively. My doctor diagnosed me with pneumonia since I was slightly wheezing, but I do not believe this to be correct.
