Possible cause to think of
 

A few months before my MMN symptoms starting showing, I had a porcine bone graft planted in my jaw, because there was a damage after a huge inflammation. I'm just wondering, if there could be a connection. Maybe my immune system rejected it and has been running havoc ever since? If that's the case, there is probably not much to be done about it now, 9 years later.

Is anyone aware of a link between a xenograft and an autoimmune condition?
