Would love to hear from patient's who have been diagnosed with multifocal motor neuropathy or chronic polyradiculoneuropathy. I have been getting IvIG infusions since 2008. I currently get them every 3 weeks. Recently I've been having more muscle spasms in my upper legs, behind my knees, and ankles. I presently see Dr. Crum in Neurology and Dr. Lacy in Hematology.
