I think because you can get RSD from an injury or surgical procedure, there are insurance companies involved. Maybe that's why. There's this sense of "blame".

Cancer is nobody's fault, MS isn't either, but RSD could be seen as someone's fault, it is a consequence of surgery or an injury, maybe that's why a lot of people are so "shy" around the condition.

Pretending it's not there won't make it go away!
