For past few years shortness of breath has been gradually increasing so that going to the mailbox causes me to stop and catch my breath now, Pulmonolgist and testing diagnosis is COPD. Never smoked, no coughing nor sputum. I have scoliosis and Xray shows right lung about 40% compressed but clear. Never get improvement from inhalers. Should this be classified as truly COPD? It doesn't seem to act like classical COPD so the usual advice doesn't seem to apply. I can no longe play golf or run. I am a 90 years old male, otherwise healthy. Does this ring a bell for anyone? Advice?
