I have to agree with what JDubbs said. Just because your PFT nmebrs went down, doesnt mean that its completely permamanent damage. My PFT's went down from 89-84-78-74-64 in like a 5 month span (from Sept 2006-Jan 2007) and now they are back to 96%! This was after a two week course of IV's then two week hypertonic saline, and two weeks of Tobi. But that low number was in January and they started to come right back. I mean, not to get your hopes down or up, but that doesn always happen. I have worked very hard to be compliant with my meds over these past few months. When I had my downward spiral I was not doing meds all the time, very rarely and luckily I, so far have been able to get that function back.
