I am a 68 year old male that finally got into shape at age 40. I have done several marathons and at age 60 I completed my first Ironman race. I have completed 3, so far.
Last year I noticed that I was having trouble breathing while running. This summer I was diagnosed with failure of my right phrenic nerve. I only had 50% use of the nerve, so my right diaphragm would not let my right lung fully expand. A sniff test confirmed this.
After another sniff test, just last week I was diagnosed with total failure of my right diaphragm. I am looking for any way to rehab the nerve or strengthen the muscles of my chest, so that I can run again.
