@lindam272 Linda, you can QUOTE ME .. the practice of an EXPERT, Dr. Timothy Aksamit, Mayo Clinic, Rochester, MN EACH AND EVERY follow up check up that I had was: sputum culture/Xray/Pulmonary Testing. This was his STANDARD practice from 2011 when I began to see him up until 2017! Plus an occasional CT scan. You SHOULD tell him that if MAYO CLINIC considers it "medically necessary" .. YOU QUESTION WHY he does NOT!! Linda .. YOU must be your OWN best advocate. Personally I would question just how good this guy is! Just how can he MAGICALLY see changes in your lungs may I ask?? It kinda ticks me of!! If I was sitting in your shoes I would request a phone call from this doctor .. WHEN he calls tell him exactly what I have told you .. if he gets huffy about it .. THAT is your answer. Personally I'd be looking for a better doctor who listened to me! Don't forget @windwalker Terri who is facing a lung transplant from years of doctors NOT listening to her! Forewarned is forearmed! You go girl! Hugs to all! Katherie
