Hi Nancy,

I wish I could tell you RSD doesn't spead. There are some in the medical fields that think it doesn't. I can tell you for me it has gone fullbody. It started in my right arm and shoulder then left arm then my torso and legs. The worst thing you can do is get too anxious about it only makes you feel worse. Ativan is great for helping with the anxiety (at least it works for me).
Keep in mind RSD acts differently for all of us. Thus, the reason Western Medicine has so much trouble manageing the pain.
I hope you find peace and just take it one day at a time.
