@tjp4 That is actually one of the ones that isn’t ruled out (or maybe not even tested yet) that I have wondered about. The one thing that I am not sure about is that I thought CIDP has irregular EMG results. My results were always “normal” but they were within the first few months of this starting. My Dr will do another EMG next month, so maybe that will tell us something. One reason I wondered about it was because the progression is slow (relatively speaking, I guess) and the nerve stuff is on both sides of my body, which I believe is typical for CIDP. How did you get diagnosed? Was it by a neurologist? What tests confirmed it?
