It probably is time to see his pulmonary doc. While this could just be the way the progression of the disease is working for him, it's also possible that he's working on an exacerbation and yo9u want to stop that as quickly as possible. At least call the doc and let her know what's going on. I would suggest that he see someone and explain what he's been experiencing. If nothing else, both of you need to know what's going on right now and how to respond to it.

Yes contact Dr also try mucinx dm will help

Whenever symptoms change you should always contact your pulmonologist.

One thing beneficial for getting the mucus up when it is difficult is an Aerobika. The hospitals call them a flutter device. They work really well. Get one if you don't have one. I hope he is involved in a good exercise program. That is also one of the best things he could do. You have to make yourself do it, but the benefits are worth the effort. That is why we have a group that meets at an adult wellness center to exercise. Most come 3 days a week. Hope some of this helps...

Mucinex helps me a lot with the exporation of the mucus. Unfortunately it is expensive, but worth it to me
