I had a canopy fall on my right foot in Aug 09, I was diagnosed with RSD in Dec 09, I had a spinal cord stimulator placed in Feb 10, everything was feeling better until about 5 days ago I would wake up to muscle spasms in my left foot and leg and now its got the constant burning and my foot feels heavy color is still ok but Dr cant see me until Monday...going crazy because Im so scared.. could this be spreading and if so what do I do?
