An x-ray is not considered a definitive diagnostic tool for either COPD or emphysema. Good you're seeing a pulmo; you'll probably have another PFT as that's the definitive diagnostic tool for COPD and emphysema. Until you get those results, I wouldn't get too excited. If the PFT is good, you might ask for a CT scan just to be sure that what was in the x-ray wasn't something to be concerned about. If it does turn out that you do have mild COPD, you might not be having symptoms now anyway and you can consider this an early warning and change your lifestyle sufficiently to ensure that you won't get any worse. No need to be confused; just know that x-rays only indicate potential for COPD; it's not definitive.

Thank you so much for your response and support!
