Thank you for your question. The Elexoma Medic Machine purports to make use of Cranial Electrotherapy Stimulation, which involves the application of electricity as pulses across the head of the recipient. The charge is quite low but there are several promising studies that have shown positive benefit in people dealing with depression, anxiety, stress, insomnia and substance dependancy disorders. There are also a few studies that show some benefit to people with chronic pain syndromes, such as trigeminal neuralgia, although these produced temporary alleviation of pain symptoms. The currents used here where in the range of 600 milli-amperes.
I have not used the Elexoma machine personally nor prescribed it and as such cannot offer an opinion on its effectiveness. I would however consider a trial run to evaluate the response of you body to the micro-current stimulation.
What I have found to be successful in the management of TN is acupuncture combined with the appropriate use of omega 3 oil and herbal supplements that support mitochondrial rehabilitation.
Many thanks and warm regards
