Lidocaine is given IV under careful conditions for systemic nerve pain. Since lidocaine is a sodium channel blocker, it works for some.
RSD patients try it, and we've had Malawigirl here get them in UK and post about it.
There is research on Nav1.7 sod channels ongoing.

There may be an oral drug in the near future. Lidocaine can affect the heart, so it is not an ideal solution. The patches may work on targeted areas, but global burning symptoms can't use many patches a day.
