Hi, welcome to the forum.
I'd never heard of Tumafactive MS before...here is one website that describes it:
I'd have to figure out exactly what they mean by that: from a brief reading of the website it appears to describe what I've always known just as relapsing-remitting MS, but maybe you have been told the difference and can explain it to us?
I think you'll find several people here who have been diagnosed with multiple autoimmune diseases. Unfortunately it seems like that happens a lot -- you get one, and others follow. But not always: I have MS, and only MS, although other autoimmune diseases do occur in my family.
The others will be along soon to chat with you.
...I am not a doctor, nor health professional, and don't pretend to be one, here.....
