@pmm I am being seen at UCSF Oncology and Neurology. It has been established that I do indeed have Anti-MAG and Cryoglobulinemia. I have been slotted in the extremely rare disease category due to the fact that my M protein is IgG not an IgM protein. I have gone through almost 10 years of testing and this has been the final conclusion. I would just love to find someone who falls in my category to talk to
