I’m a 69 y/o male, active and healthy, good BMI, no history of pulmonary problems, non-diabetic. One coronary stent for non- typical blockage. Have had a chronic non- productive cough, several months. Steroid taper, levoceterezine no help. Blood test shows abnormal A. Pullulan which can point to many underlying causes for the dyspnea. I have an appointment with a pulmonologist next week. Would like info on further diagnosis and treatment. Michael
