I realize that this response comes many years after the question was asked but YES, RSD can and does (for many) spread. Drs. Robert Swartzman and Anthony Kirkpatrick (you can search for them online) can most likely provide you with written studies proving this. Dr. Swartzman is in PN and Dr. Kirkpatrick is in FL. Sometimes the disease never spreads (lucky folks) and others may not spread for years...others (like me) have very rapid spreading of this demonic disease. Mine began in Feb '09 and was full body by Dec '09. I was hospitalized in April of '10 with internal bleeding associated with the RSD.

Good luck,

I am 16 years old and I was diagnosed in March with CRPS only after one month of the initial pain. They still aren't sure of what caused the pain in my arm but already 3 months late I am a lot better then before.
However due to this two other medical problems have come up so I am having to deal with that and school work.

But for right now I am really just wanting a place to talk to people who understand the pain and everything I am going through. While I know my parents and friends love me and know something is wrong the second hardest part of all this is the loneliness.
