I have axonal sensory motor polyneuropathy plus MGUS. Is this the same as anti-MAG? It sounds very similar. I also have the balance issues, heat-related weakness and trembling, plus cramps in my calves at night. I'll be seeing my neurologist tomorrow because the balance issued had worsened (but is better now), plus when walking I have what feels like bruises on the bottom of my heels, and weakness in my ankles (probably since I don't have any reflexes in them). So, is this the same thing or similar? It sure sounds similar.
