I forgot to mention(blame the Lyrica)....As I understand it, phrenic nerve involvement, whether reported or not, is one of the top reasons surgeons want to wait at least 9-12 months between surgeries on each side. They want to make sure the phrenic is fully functional as it controls your diaphragm. While some of the other nerves in that area are easily identifiable because of their size(think pencil or larger), the phrenic is about the size of a pencil lead and much more sensitive to manipulation.
