I saw my pulmonary again, he said my chest pains are from coughing, I was still producing lots of mucous, white thick, some yellow, plus brown
/rusty speckled phlegm
. He took another chest x-ray for comparison, said it was fine, just like the first time. He told me the brown specks are "old blood", he gave me a 5 day steroid treatment, which I finished well over a week ago - I do feel better but I am still coughing up "old blood" and I am extremely worried.
