When it spread to my arms all I had was the pain, no temp or color changes. I was unsure of the whole deal. I talked to a good friend of mine and she had the same thing for her arms and places on her body. Just pain but no temp or color change. I had pain in my arms/hands/shoulders for about 2-3 years before the color and temp changes happened.
I have no temp or color changes on my body, just pain and burning.

Hugs,

Karen
