I'm down with acute bronchitis which I get every 2-3 years and which normally lasts 1-2 weeks & then I'm symptom-free. i'm on a round of Levaquin 7 days) and prednisone short term (5 days) covid test negative and no pneumonia, however on the chest X-ray was written "signs of COPD changes." What the heck does that mean and how is COPD really diagnosed? I'm an ex-smoker, stopped in 1982. The bronchitis cough seems more resistant than usual this year and I wondered about COPD..
