Hi, I am new here and a little nervous. I was put into the hospital on Nov 7th for shortness of breath. They did a bunch of tests. They ruled out pneumonia. I went home on the 12th on 24/7 oxygen. they are now putting me on prednisone. They are not sure what I have and I am scared. Dr. said the steroid will increase my appetite and most likely gain weight. I can't gain weight. I am already quite overweight. I am in a deep depression. I need some advice from you to how to deal with being on oxygen 24/7 and with unknown lung problems. I am at a loss, I don't want to be like this. Can anyone help.
