Hi Colleen, Thank you for your reply. I am just wondering what percentage of people with bronchiectasis have or develop MAC as that is what is most of the posts are about. I have some sputum production but very seldom and no other symptoms that I can tell. No testable decreased pulmonary function. Am on nebs and aribika now. Had second Ct scan that shoes bronchiectasis with numerous mucous areas and one nodule that they are following for changes. Does that mucous sitting down there create infection that doesn't create overt symptoms? I have tried to get ahold of my clinic to clarify things but they are not responding and I won't be seen for 3 to 6 months. I am registered to eventually come to Mayo but was going to wait til fall. Now think I should try to get in sooner. Just presenting the thoughts that roll through my head. Thanks for this site and listening.:)
