I, too, have bouts of facial (trigeminal) neuralgia. I have the scalar and sleep in the field nightly but it didn’t seem to relieve my pain but I used only pure scalar with no meds or oils being transmitted. I did use my mini magic device, stacking the coils and placing them just in front of my ear. Within a half-hour, the pain was completely gone. I felt it coming back a couple of days later and repeated the process and it has been gone completely! Love my mini magic and my scalar!
