Hello. Does anyone else find that wheezing and crackles on lungs and coughing up green yuk does not always mean its an infection. I am slightly confused that every month so far i am put back onto antibiotics for this but xrays are clear an nothing grows on sputum samples.

"Your mucus can also change color when you're sick. Green mucus is a sign that your body’s immune system is at work. The color comes from a type of infection-fighting white blood cells."
