My sputum is almost always yellowish green. When I go on antibitics it will be white for a week or two and then it goes right back. When I feel good still have the color to my sputum. I just don't produce as much. Is any one else like this? I can remeber a time that I didn't have color to my sputum when I wasn't on antibitics. My doctor doesn't seem to be too concerned. He hasn't done anything drastic. I have only be on IV antibiotics three times and weeks later I had yellowish green sputum...Am I alone in this?
