@picartist The pale green mucus can be a constant thing with Bronchiectasis. It’s not necessarily a sign of infection. If you cough up more or it changes colour and especially if it gets thick and sticky and you have other symptoms, all that might be a more accurate sign of infection.

Otherwise, it is probably chronic inflammation. I’d like to know why the chronic inflammation in mucus is coloured.

So unfortunate that some doctors don’t know that coughing up yellow / green mucus for longer than a few weeks can lead to chronic inflammation that might be a sign of other chronic conditions, like Bronchiectasis.

Many just shrug their shoulders and state that green mucus isn’t always a problem. Problem is, when it is an issue, it is often then chronic and we live with the consequences.
