Vicc,

I don't believe anyone implies that RSD comes as the result of 'a nerve injury' except of cause for CRPS type 2.

I believe that RSD/CRPS is usually the result of some initiating event in or to our bodies that sets off an unusual response by our sympathetic/autonomic nervous system .To find what allows some people to succumb to this disease where others don't, would indeed unravel the puzzle of prevention and cure.

Not everyone who has RSD/CRPS has had a reperfusion injury as they have not experienced an ischaemic event which causes IRI. Nor do all people go through the stages of RSD/CRPS that you have suggested in your post to Carrie.
