I also, usually have clear to yellow mucus when doing my lung clearance. Every once in a while slightly green. I notice that usually happens if I eat peanut butter, nuts or a lot of bread products. So I think the same thing about the different colors. But right now, unfortunately, I had some hemoptysis yesterday. So I’m feeling a bit anxious today. Went to my Dr, had an x-ray, no changes since last year. So that’s good, and I know It is a symptom of bronchiectasis, but, it still worries me a little. It hasn’t happened to me like that since the first time 3 years ago. Hoping it doesn’t happen again.
