hi mermaid and welcome
i have rsd full body and internal now for 11yrs. i get very little relife from many treatments i have had SGB on and off for 10 yrs also lumbar blocks. i have had a bier block that they do use that turniquet time thing to do the block this was very early in my rsd. and i didnt know better it just made me worse. Karen blocks have made me worse. given me flares. i like you am weird about things my sister laughs and calls me a freak of nature lol. where do you live mermaid. ? i also refuse any needles in my arm or side that my rsd started
