Hi I am sorry you are having to face this. Are you on any meds or have you tried any? Where is your rsd? Was it a pain management doctor who did the block and did they know a lot about rsd? I have seen a couple pain docs and have gotten a range of treatments to do. It is very key that they know a lot about rsd. Hang in there and I hope you find relief soon and better direction in treatment. You can email me too if I can help in any way I will try or if you just want an email buddy
