My pm dr wants to give me nerve blocker injections. I have chronic pain from a cervical fusion that is not healing. If I didn't feel the pain I would have never known it wasn't healing and went on with life. The pain is how I found out it isn't healing or at least healing very slowly. My dr has already given me three the limit sterroid shots in my shoulder which is injured, I am also diabetic type 2 and have high blood pressure, alot of numbness in arms and hands and severe pain in neck and shoulders. Is this safe for me, I have heard bad things about nerve blockers and I am supposed to get this done on the 19th thinking about cancelling the appt and finding out more info. I don't want anymore permanent damage than I have already aquired from this injury. Any input would be most helpful...thank you
