Hey, all, I asked the above question in my thread about learning something today. Several people gave their answers there, but I'd like to know - especially from those of you who are in the medical field. Does the color green in our sputum: from the sinuses or from the lungs invariably mean infection? I was in a really bad spot, with what I figured was pneumonia, and my regular doctor having suddenly split town. In my other thread, I explained how the one thing that persuaded the new doctor to prescribe antibiotics was the sample I had brought of the green stuff from my lungs. Someone questioned that kind of "proof." Hence my question to all of you.
