Angela,
I also credit IVIG for my great improvement. This time last year I was wheelchair bound. I received monthly IVIGs for three consecutive months, (Jan.-March 03). I now get around using only a cane. I also take several other meds including Prednisone & Methotrexate.
There is treatment for Myositis. The following are a few links to wesites with more info.

I hope this helps you.
