So sorry that you have recieved a diagnosis of Fibromyalgia, Desi ((pain-free hugs)).
I haven't been officialy diagnosed with Fibro, although I do have a lot of the symptoms such as fatigue, tenderness in certain spots etc. I read somewhere that you have a much higher risk of developing Fibro if you have RSD or other chronic pain conditions and that in a lot of situations RSD and Fibro go hand-in-hand.
I wish I could help you more, just know that we're all here for you if you need anything.
Pain-free hugs

Alison
