You bring up some good questions. No, we don't know if I have NTM or MAC because no one has done a bronchoscopy even though the doctors in the hospital suggested it. And apparently the assumption on discharge from the hospital was that since clinically I felt better, had no fever, wasn't coughing, completed the 14-day treatment with antibiotic and only got SOB with real exertion beyond my normal activity I was cured. I told my pulmonary doctor that since doing all that I came home, felt great at first and now need to use oxygen more than I ever did and at a higher level! But where do you even start to find someone with the skill and knowledge to treat those things?
