Hi there,
Yes I do notice uncontrolable muscle movements. My toes spasm and my leg shoots out in front of me whenever I am walking. It is horrible and really embarrassing. The muscle up from my big toe cramps all the time too.

I don't think the spasms are anything to be really concerned about I think it is just another side effect of the RSD. I would speak to your PM doctor about what you are experiencing though. I was and still am really concerned about my balance problem, my PM doctor says that he's never seen it before with RSD.
Hope this helps and if you need anything else just ask
Thanks
