Scrambler. It is the use of electrical stimulation to send a signal to the brain that is a "non-pain" signal. So the brain still receives the signals from the nerves, but interprets them as non-pain. My non-technical way of explaining it is that the radio is still on, but you've changed the station, so you are still hearing music, but it is a music that doesn't cause you pain. It is being used for nerve pain resulting from various conditions including peripheral neuropathy, demyelination (transverse myelitis, clinically isolated demyelination syndrome, MS), pain resulting from chemotherapy, and complex regional pain syndrome. There may be other conditions. These are the ones I know of. It has been around for about 20 years and in the non-research setting, it is called "Calmare."

It does not work for everyone. But it is non-invasive and if your situation is like mine - you've tried everything else and nothing worked - it is worth trying. In my case, the only program at the research hospital using Scrambler Therapy is the palliative care program in the oncology department but they are now adding it in the neurology program, the pain management program, and (I've heard), the physical therapy program.
