I am starting to get a little discouraged with my emphysema (stage III- Fev 43%). Was diagnosed 9 years ago with mild & went on 02 last year. I was doing good by walking everyday for 30 min and trying to be more active. But last month it seems like it is getting harder and harder to breathe even with my oxygen. It is just not SOB, I feel like I can't get air in. I have to keep taking a break until I get my breath back. I go to Dr in 2 weeks and will talk him about it. I am just hoping this is not a sign of getting worse. I am on Symbicort 2xday and Sprivia. I am going to keep fighting it, just kind of let down. Anyone who can share your experience will be appreciated.
