Trigeminal Neuralgia (TN) is an attacking, abrupt and electric-shock headache in the realm of one or two branches of trigeminal nerves. It is one of the most severe neuropathic pains ever known. By considering main known regions of the brain involved in TN, we made a conceptual model named TN pain neuro matrix. Then we took an external stimulation into account and assayed the different possible approaches about how it may be concluded to pain relief.
