Hi welcome to the boards though I am sorry you are facing this. The block for me made my pain increase. So right now I am back to meds like neurontin and trying to keep mobil and decide my next step. Are you on any oral meds? I am sorry you have to wait for approvals. I can't even imagine how stressful that is. Does the doc who did the block deal a lot with rsd? I hope and if not I encourage you to try to get in to see someone who does. It is very key in my eyes. Feel better and hang in there.
