I am afraid that I have COPD. I have been coughing for years. I get a feeling like I am short of breath only while I am talking, and I constantly clear my throat. I also cough during workouts. Sometime a lot, sometime no cough at all. I exercise 6 days a week doing HIIT traing and P90x. I am never short of breath during strenuous exercise. I am a fit, muscular 38 year old male, 6 feet 1inch tall and 190lbs, I have chronic sinusitis and post nasal drip. I had a pretty recent x-ray that showed peribronchiial cuffing. ( I work with Radiologists and they said it means I probably have an asthmatic like condition). I have had at least 25 people (doctors, respiratory therapists, and nurses) listen to my lungs at different times and no hears anything but normal breath sounds. I have never smoked, drank, been exposed to chemicals, or been exposed to second hand smoke.I have a PFT scheduled for 6-24. Does this sound like COPD?
