Hi Tom,
I have had symptoms since 2002. I was also told I have ALS by a neuro Oct 31, 2006. Dec 7, 2006 the ALS specialist wanted to see if MMN, by giving me IVIG. So my story is the same as your in parts. I have no anti bodies in my blood, and only LMN. I may have one conduction block, but not two. I have been on IVIG twice a month since Jan 2007. Overall there is no subjective change either worse or better, but the NCS does show some improvement, which it would't if I had ALS. So that is the story. I am not worse or much better functionally, so it seems the IVIG is keeping me steady. This is very good.
I hope you have great results with the IVIG. If you do have side effects, there are many things they can give you, so make sure you ask. Let us know how it goes.
To all others, Patty etc. thank you so much for your kind words and good wishes. Sincerely, Peg
