Page "Complex regional pain syndrome" Paragraph 2

* Type II, formerly known as causalgia, has evidence of obvious nerve damage.

It should be noted that most information commonly available about CRPS, including this Wikipedia source, relate information more accurately about Type I CRPS.

It should be noted that Type II CRPS tends towards the more painful and difficult to control aspects of CRPS, and the three main types of CRPS listed in this article relate mainly to Type I, also.

In Type II the " cause " of the syndrome is the known or obvious injury, although the cause of the mechanisms of CRPS Type II are as unknown as the mechanisms of Type I.
