Mine were different nerve blocks that are for a diagnose. A little bit different than the ones to block pain.
The ones I got were administered in my ganglion bundle to see if and what nerves were actually affected by RSD and where.
If I proceed with a SCS than that would be like a block blocking pain signals.
Tests showed that nerve blocks done to another area besides my spine wouldn't last long enough to make the effort worthwhile.
Everyone differs when it comes to their specific treatment...
