oh desi i am so sorry the sgb wasnt as effective as it had been before. did your doc alter the mixture of meds they injected...the only reason i ask is because over the years i have had intrem docs while my real ones were out of town who used different ingredients for their block. my pain doc has also switched things out a couple of times after reading about the superior effects of the new solution....needless to say we went back to the tried and true old school method that has been proven to work.
good luck
you are so close to that moment in a pain patients life where they know its there but it doesnt interfere with what they are doing i truely hope your docs can figure it out and get you back on track
