Thanks for all your contributions/wish I had more! Anyway, when the injection goes through my back, what if my limb doesn't warm up and should it happen immediately? Will I feel immediate relief and will I be able to tolerate someone touching the leg if it desensitizes? If it doesn't warm or if there is no immediate relief, does it mean I don't have CRPS or that the diagnosis should be questioned? I'm taking this block a year later than I should've because of uninformed medical professionals so should anything that comes out of it be taken with a grain of salt? PLEASE HELP!!
