O my dear...... I fully understand you on that fear. After my accident and learning that my life was going too be constantly run by meds n drs. I was scared as  _______ You can be assured of that one. I hated drs n medicines totaly.. With the drugs that I was being given n not understanding all the whys or how comes i certainly had too look n find answers.  Certainly was maddening that the drs wanted too preach about my cigarrettes handing me drugs in other hand... Well,,, question that come too mind was what could be worse,,, drugs or ciggarrettes????  Did not get no answers on that one.. No more preached at neither..  So that is my experience with the drs on that . I certainly can tell you,,, I had 42 blocks done  rsd did not spread.  They did help alot.  And the discoloring also was helped alot.  Now had 8 more done and  helped again tremendously well.. Going in for follow up this morning now... The pain is all coming back now n is much much different so this is going to be nex experience for me now.. also a new dr  since mine quit here at this office... Hate that he quit.. Was doing me so well.  He gone,,,, I am so thankful that he did help me..  Really!!!!!!!  Hoping that u having a good week as is possible... Annie
