Joanna,

The other thing to remember is that a skin biopsy can be repeated in 6 months (normal time period to really tell if helpful) to see there is an increase in nerve fiber density...this is "proof" it is working. So, even at 6 months, your symptoms may only be somewhat better and density slightly increased...but it is signs that the IVIG is working and you are headed in the right direction. IVIG takes TIME.
