Just a little fyi... not all Type 1 stays where it began or spreads slow....

I have Type 1.... mine has spread faster than any doctor I have been to has ever seen... is full body with internal organ involvement.

Type 1 also referred to as Reflex Sympathetic Dystrophy - cases in which the nerve injury cannot be immediately identified.

Type 2 also referred to as Causalgia - cases in which a distinct "major" nerve injury has occurred.
