3 weeks ago ideas rushed to hospital because the co2 in my body was 98%. I didn't even know at the time in was in so much trouble. Just having shortness of breath. Well here I am in rehab and going home in 2 days. Still have problems breathing , that has been that way for 6 months, never seems to get much better unless I'm on heavy prednisone. I'm so afraid this will happen again and wont realIze it. It's really freaking me out. I see an allergist in June because right now I'm allergic to the meds they use on me, so I have no inhalers or nebulizer. They say now after this I'm fourth stage. I have been exercising everday while in here but don't really notice a difference. The girl's say they see a difference I am getting stronger and doing better but I think they are just trying to make me feel better. Really really scared.
