I have had bronchiectasis for around 3 years & was recently diagnosed with mycobacteria abscessus. The lung specialist I have just seen is not real keen on prescribing a nebuliser (I am in Australia). I have just found a pulmonary rehab centre which I am hoping can help me with ACT. How safe is it for me to "self treat" with a nebuliser? I would obviously need help with it but don't know where to turn for help. I'm hoping to see a respiratory physiotherapist through the Pulmonary Rehab clinic.
