Hello swimtime,
Welcome to the NeuroTalk Support Groups!
I'm so sorry to hear about your son. That's so young to be dealing with such a painful condition.
There is an
RSD/CRPS Forum
At the top of the forum there are "Sticky" threads and they include information, useful websites, introduction thread and other resources.
I'm sure the members there will be able to help you with lots of support and information.
