For the last 3-5 months I have severe pain in all of my main muscle's! Have goggled a lot regarding this! Some of them say Fibromyalgia (sp?) Low levels of vitamin D. And it just goes on and on about what it could be? I just want to know how many of you have had this severe pain? Also what your Doctors told you what it's from? I have had full body RSD now for over 10 years now. Hoping all of you courage of spirit strength of body and peace of mind to move forward! Breezy55
