Thank you for your time and information. I have an appointment with a pulmanologist the 19th of August. So anxious to hear what he has to say. I had not heard about phenic nerve grafting and very anxious to pursue this info. I have labored with this problem off and on for some time . Considering some of the side effects...i wake up at 4AM , weight gain..."heavy breathing"...heart burn, etc...I think the doctor in the xray department who did my "sniff" test was correct in saying this has not just happened. But, thanks to an alert and pursuant hospitalist this was found and now i am on the road to finding what is the next step. i would appreciate any information from those having this condition and how they cope with it. I am a person who just keeps on keeping on and not sure what to do with my "Keep ONs" I might also mention , I have fibromyalgia that was diagnosed by a rheumatologist at least 30 years ago. I am not sure how this may affect my diaphram ...maybe not at all. thank you again....
