I have a cold. Yesterday I coughed up a substance that was rubbery white with streaks of blood but I felt a lot clearer congestion wise. Today I am a lot better the phlem I am coughing up is clear or a little green but is leaving a metallic taste in my mouth. Could this be from the gufesein that I have taken or something else. I am feeling a lot better. My sysmtom or congestion, ear ache, no cough and my fever is gone. Sorry for my spelling. I am female, 31, weigh 270 height is 5'8
