Has anyone experienced wheezing and or the inability to breath as deeply as when they first got transplanted? My doctor prescribed an albuterol inhaler because my PFTs were down in the morning. It helped some. We recently checked for rejection and thankfully, there was none. It feels tight at times and I find myself puffing a little bit more. I can still exercise but it feels different. Also, it doesn't happen every morning. My PFTs are all over the place. Is there a plug that I can't get loose? It's worrisome.
