CRPS isn't that new - when I clicked on this thread I thought we were getting a new name for this lol! Over here CRPS is more widely accepted I think. I prefer the term CRPS as it describes the condition clearer to me personally and so I identify with it better. The "regional" part is a good descriptor as for most it starts that way and spreads that way. When I've used the term Reflex Sympathetic Dystrophy, people have needed more of an explanation and wanted to know what's wrong with my reflexes and why I want sympathy for it (har dee har har). I read however that some docs call it "craps" and that bothers me, crap as this disease is lol! I don't like the term RSD, I think it's vague and I don't identify with it. It also bothers me that most printoff info is American and therefore often labelled RSD and I have to then explain that it's the old name for CRPS.
