Zack,
Yes he did do a nerve study, Both doctors said that what I have is either early ALS or Multifocal motor neopothy (MMN).
I asked if I was to young for this disease and he said there are teenagers who have ALS and after looking thru this forum there is a lot of young people here also.
I am still awaiting the call from my doctor to go to Mayo.
Another thing that was interesting is when I did my two cycles of IVIG my right side improved but my left side did not & my twitching went down after the IVIG session and returned about 11 days later (after the IVIG treatements were over). Have they suggested you might have multifocal motor neuopathy?
