Hi there,
I am a twelve year old girl who suffers from RSD in my right arm and left leg (my leg is much worst than arm)
I have not heard aboutRND but from what I understand, it is another word for RSD, it certainly sounds like RSD in my opinion.
I found the PDF very useful, and I am sure many more people will.
Many thanks for posting this message it was really interesting
Pain free hugs
Alison
