Hello, I was diagnosed with genetic COPD 7 months ago. My family does not believe me and is making me feel confused so I have been researching extensively. I do have a lot of symptoms of COPD like coughing, mucus, broncial hyperresponsivness, dizziness, short of breath (especially stairs). I also have allergies. What is the difference between COPD and Asthma? Could I have been misdiagnosed?
