paralyzed diaphram

After experience a sudden shortness of breath upon exercising and after a battery of tests including CT scans of the lungs, xrays, heart cath, a sniff test and most recently today a brocospopy (?), the pulmonologist says he has a paralyzed diaphram.  Since he has not had a recent surgery, as noted in some of the other questions, the doctor is at a loss of what could have caused it.  She has suggested a test for lyme disease.  Is this a possibility or is she just grasping at straws at this point.  Is there any cure for a paralyzed diaphram or is there any surgery advised?
Thank you
