I'm seeing a pulmonary specialist right now. I'm on oxygen 24 7 since November 2015. I was hospitalized for a week in Dec. but I don't have a diagnosis. I seem to be getting a little stronger but if I take the oxygen off to take a shower or climb stairs I am shakey and my finger tips and nails start to turn blue. I am taking 25mg of Prednizone and the nebilizer 2x a day. I have alot of mucus and cough alot also. I feel like there is something between the back of my nose and throat that is causing some kind of blockage
