Thanks for this Vicc.
I agree that more research needs to be done about RSD, there isn't that much research going on at the moment.
I think that the fact sheet by the National Institute for Neurological Disorders and Stroke (NINDS) is accurate, it tells you a short description about colour changes, it is good because young people like myself can understand it.

I have tried many supplements including Grape Seed Extract to try and help reduce swelling but they don't seem to work. The swelling in my leg goes down every so often but then it comes up worse than ever, I only developed swelling after a Guanethidine nerve block, and I have later found out that my PM doctor thought I had compartment syndrome as a result of the block.I am also experiencing horrible colour changes which I didn't have before.

Thanks
Alison
