Hi Cliffman,
I am sorry to hear your symptoms are spreading. It seems odd to me too that SFN would be acting this way so quickly.
I had mentioned CRPS when you came on board and I saw that Jo*Mar did as well. Since CRPS does sometimes arise after heart attack it makes me wonder about this possibility.
I am attaching an interpretive article from RSD Hope's site about Dr. Louise Oaklander's findings on small fiber damage in CRPS 1. I had found the actual research article some time ago but can't locate it right now.

This might be something to consider with your doctors.
