Thank you. I've taken that test before. It says I have TN2 which is another name doe Atypical Facial Pain. I've found some explanations of Occipital Nerve Stimulation. From what I can gather, that is a type of Peripheral Nerve Stimulation. So I guess that for the trigeminal nerve it would be similar, but focusing on the trigeminal nerve not the occipital nerve.
If anyone knows of any study results available for outcomes with the trigeminal nerve - please share the weblinks or reference info.
