so chances are it really is traveling down my back without going down my right arm then.. my neuro wants to test me for fibro, she said that crps dont spread therefore the name regional. and it really made me mad when she said that.. I know my back is on fire, i can feel it burning. It hurts.. So she cant tell me it doesnt spread. I just needed clarification on which one i could possibly have.. So i appreciate all the responses.. Keep smiling any info you could pass along would be greatly appreciated since i have a deep misunderstanding of what is going on inside of my body and cant get any answers except on here at this moment.. Was trying to get into this dr that does ketamine and they sent my file to a dr that wants to take me off pain meds,(which i dont have) and put in scs. I really dont want that..
