After 10 years of diagnosis of monoclonal gamopathy and noone suggesting any help, I went to another neurologist who did blood tests and diagnosed me with antimag. I have had 13 plasma pherisis treatments since April/09 and have seen positive results. Not huge overnight improvement, but slow and I am walking better. I want to mention that during the last several years I have exercised 3 times/week swimming laps and really working legs and feet hard and I believe that this has helped recovery; i.e., keeping the muscles in good shape.
