Hello An- Sum,
Welcome to the NeuroTalk Support Groups.
Here's the link to the
Reflex Sympathetic Dystrophy Forum(RSD and CRPS) Forum
There's also lots of info in the "Sticky" threads at the top of that forum as well. e.g. information, useful websites and links etc.
Always good to see another Queenslander

...
although I'm sorry for the reasons that bring you here.
take care
