i am 47 y.o. and smoked for about 30 years (about 30 +/- cigs/day)..i just had an x-ray and the results came back as hyperinflated lungs possible emphysema or COPD...it has been a year since i quit and many times i have problems taking that one deep breath we sometimes take and it seems to be accompanied by a lot of yawning til i can take the deep breath...my doctor wants me to take some pulminary tests (why??) as my blood pressure was in both arms 100/60 my heart rate ranged from 47-52 (and 60 with this doctor)...so does this mean it's all down hill from here? or can my breathing and lung capacity improve? and is it possible the x-ray could mean something else??
