My name is John and I was diagnosed this past January with a paralyzed right diaphragm. Phrenic nerve damage has been ruled out because of the amount of time between my heart valve surgery and when this started. I still cannot figure how this happened, I have a couple of ideas but nothing conclusive. I have seen two pulmonary doctors and both say there is a surgical procedure that can be done but no guarantee that it will work. I would like to know if anyone out there has been diagnosed with a paralyzed diaphragm and if they had it fixed.
