I was dx with MGUS in 2002. Had a very high IgM spike of 1400. Did not recieve treatment as I had no symptoms.
In Nov. 2007 was dx with CIDP and now in Jan 2008 was dx with Anti-Mag IgM with CIDP variant. IgM remains high. Have been looking it up on the web and have a lot of questions for MD next visit.
My spinal tap also was five times higher than normal and NVC/Emg showed severe demyelination with some axonal damage and inflammation.
