@Imh7 Dr Leventhal at Mayo. I told him I was nebulizing and he responded that nebulizing is a "good basic treatment for (my) ongoing mild bronchiectasis to help control symptoms of cough and sputum." Also a suggestion of the acapella- green (not aerobika, my earlier mistake) to help clear phlegm. It was suggested that once I get my acid reflux under control and my airway symptoms are better than the nebulizing could be reduced or possibly stopped. I think it is all a matter of how severe symptoms are but as he did say in response to a comment I made about nebulizing...."it can't hurt." I personally would prefer overkill just to ensure I am doing everything I can to keep Bronch & MAC at bay. My original, local pulmonologist said absolutely not to nebulize...I did not believe him and got a script from my GP for the nebulizer/saline. I feel it helps...and am glad I can now rest easy after seeking advice from a professional at Mayo. Maybe you need a further discussion with your Dr. for an understanding on his thinking? Do you cough or have phlegm. Also wondering if you have bronchectasis ?.
