Do you know if a person can develop fibromyalgia after 5 years of chronic pain? I have RSD on the whole left side of my body, but for the past three months or so I have had a completely separate pain... a whole body ache. The doctor has ruled out severe iron deficiency or my anemia worsening. The two points where I have the most pain are my hip, which seems to radiate out to my lower back and my shoulder blade. I am unable to wear certain types of clothing on these areas because it hurts too much...but it's not at all like RSD pain. Could this be a fatigue syndrome?
