@marcwall ... In addition, I forgot to mention this. If someone has high IgM monoclonal cells in their blood (while being diagnosed), they can do an Anti-MAG Antibodies test to confirm if those immunoglobulin cells are infiltrating your nerves. My test confirmed they were (at least in-part) causing my neuropathy. So, that helped guide the proper treatment for both the cancer and the peripheral neuropathy. Killing two birds with one stone!
