Stellate ganglion blocks could very well help you even though lumbar blocks didn't. A result in one area does not dictate the result in other areas. I was put in remission by SGB's back in 1991, but they didn't help when I developed RSD in my hands and arm. I think that was because it was too late for them. I had such a good result from them in the beginning that I had to try them again. Everyone is different.

So sorry you are dealing with this. I hope you find some relief soon!
