Hello di2005, I have read some of your posts and also have MMN. Symptoms started about 1 1/2 yrs ago in my left foot then progressed up my leg. I started IVIG in January 2009. I can still walk without assistance, but limp quite badly if I try walking too fast. I too am searching for "what else" beside IVIG. Just wanted to say "hi" ... good to know we aren't alone in this battle.
