I really appreciate all of the information. Seems This is such a diverse and enigmatic disorder. No one even seems to try to find causes. I have been trying to get to the bottom of this for over two and a half years. Was misdiagnosed with a disk problem and had back surgery and finally got the CIDP, MMN diagnosis this winter and have just now gotten approval for IVIG from the insurance. Just in the nick of time as I can hardly walk even with a cane. I will let the forum know how thew IVIG treatments work out for me.
Thanks,

PS Insurance finally relented after I had a Spinal Tap with positive protien marker. FYI
