My doctor seems to blow off the fact that I am coughing up black stuff and I am not happy. I don't smoke and I don't hang around with people that do. I use to though (many months ago) so it seems that he is judging me to just assume that I do now. He says nothing shows up in the xray. I am thinking of just getting another doctor. Has anyone else coughed up black stuff, if so, what were you told it was? black girl prom dresses
