I've had RSD for 14 and a half years, controlled with pain meds. It's in my left foot, ankle and leg. The past few weeks, my calve has been hardening, like an involuntary muscle spasm. It only lasts a minute but it's like my ankle locks up and all the muscles around it and the leg. It does NOT affect my foot. It usually happens when I'm sitting or sleeping.

So far I've just been able to massage it or it lets up on its own after a minute or so, but it's scary. It's started happening during the day now and even as I type sometimes. Is that what muscle atrophy is?

I mentioned it to my doc, that the muscles were bothering me, but he either didn't hear me or wasn't concerned, though he looked at the leg. I've done so well for so long that I don't really know what to expect at this stage. After all these years of RSD I KNOW I've been lucky to have the pain under control, lucky to be working and living a full life. But I worry every time this muscle thing happens b/c I do not want to end up in a wheelchair, or amputating my leg or having it spread.

Has anyone experienced this before? It's a tightening, and it's like it has control, not me. It isn't overly painful, just scary. Anyone?
