I too have no blue color in either my feet or hands. However, my feet are bright red on the soles especially and burn like crazy. My hands are somewhat pinkish. The RSD Dr. observed that both my hands and feet were the colors that qualified for an RSD diagnosis in those areas. So I guess they don't have to be blue to qualify for RSD diagnosis. Mine were never blue although they were burning like crazy.
Yes, the fibro. responds to nothing - narcotics, anti seizure drugs,etc. I think sometimes the fibro. pain is worse than the RSD. Yes, they are 2 kinds of pain but do overlap. The fibro is such deep aching, RSD is the burning, stabbing. Yet I read where fibro can do that as well. Very confusing to have both as a diagnosis.
