Mom of cf princess, I am so sorry to hear this news!!!! I can tell you that I do think I am improving some in terms of the tightness in my chest and the feeling of not being able to take a deep breath as if there is a band around my chest. I too was on the tobi podhaler for three weeks until I just couldn't take it anymore as I posted earlier. I came off the tobi around July 20th or so and they moved me to cipro which I think did its own damage as one of the side effects can affect the elasticity in your body so the tightening worsened. When they realized that didn't do anything, they put me on two weeks of IV therapy. I went from 62% to 67% but that wasn't really the change they were looking for (although I am grateful for every percentage I can improve). I truly believe what I experienced is side effects as I have never in my 40 years felt anything like this until being on that stupid podhaler followed by cipro. Following all of this treatment, the Dr realized that the antibiotics weren't working, so they did a 5 day 40mg prednisone pulse treatment two weeks ago to see if that would open up my airways. So the good news is that last week, I started to see some improvement in how I was feeling. I still have some days where I feel tight in the chest and like I can't inhale all of the way, but I am seeing improvement slowly. I am trying to really flush my system out(in the event that these symptoms and loss of function are due to these meds)and I am drinking 3 liters of water a day (or trying anyway), usually I get in at least 2+ and I am exercising as much as possible to try and flush these drugs out. I am also doing fruit and veggie smoothies with kale and probiotics to clean out my gut and replace all of the healthy bacteria. I retest on Friday and will let you know how it goes, but I want to encourage you that I am seeing improvement even though it feels very slow. I pray that your daughter will see improvement also. It is so scary any time we lose any function! Praying for you all!!!
