Im not sure if the two are corrallated, but i have to have my second nerve block done tomorrow. And i am a nervous wreck, don't think it would be as bad if it was the same doc. But since i have moved i had to start all over. The pain is so great today i cant even rest my foot on the bed, have to keep it elevated. So does stress cause the rsd to be worst? And on a side note i sit up in my bed alot with pillows behind me and today when i sit back it feels like i have a heating pad on my back that is burning me! There is nothing there but pillows! Anyone ever experienced this! My rsd is in my right ankle and i have had that happen there but not in my back.
