I also have a paralyzed diaphragm from the chemo CHOP. It is stuck in the middle of my lung. My heart was also damaged from the chemo. I have COPD last stage, so all this is very hard on me! They say if they could get my diaphragm to work, I wouldn't get so many infections in my lungs! I heard they are using pacemakers to hook up to that nerve. What problems are you having?
