Chest X-ray shows hyper-expanded lungs …COPD?

Chest X-ray shows “hyper-expanded lungs with flattening of diaphragm…consistent with COPD”.

I am not smoker, 51 yr old male…no cough, no wheezing, no asthma, no mucous.

I do have joint pain/fatigue for 20+ years from chronic fatigue syndrome. Past chest X-rays were always clear. Breathing generally very good, although recently have noticed some shortness of breath upon exertion.

Questions: -Does this sound like it could be COPD? I am going in to see my doctor for pulmonary test in 3 weeks. I know that will be more telling. Just surprised if that’s what it could be.

- Are there other causes of COPD beside the obvious (smoking, environmental exposures, genetics, etc?)

If it’s not COPD, are there other causes for hyper-expanded lungs/flattened diaphragm? (I have o history of emphysema, bronchitis, no cystic fibrosis).
