I was very short of breath before surgery, but it was due to my valve failing. After that, I was fine until about a year ago, when I noticed I was getting short of breath again. My valve's fine, so that's not an issue, but I did tell my cardio that I have felt as if my lungs never fully recovered from surgery. We did a PFT, which showed "mild obstructive lung disease," but we didn't follow up on it until this past December when I got really bad bronchitis and saw my GP, who put me on an inhaler. She wants to run another PFT to determine if I do indeed have asthma before putting me back on an inhaler/switching meds.
