Hi, my mother has Trigeminal Neuralgia. This is what has helped her: B12 (METHYLCOBALAMIN) form. This form is absorbed better. Do not use the cyanocobalamin form, as it is not absorbed well. She uses cherry flavored sublingual- 5MG. No stimulates: No caffeine, no sugar, no alcohol, and no foods that are stimulates such as mushrooms.
We have also noticed that here in TX where we live, when the seasons change from hot to cold-- it flares up. Every October is when it changes from hot to cold, and she has problems with it then and then again when it starts to get warm. We are wondering if the barometric pressure has something to do with hers acting up. She has had it for a long time now. She first noticed it after her teeth were pulled and she got dentures.
She recently added fish oil to take also to see how that works with the B12. If we see more improvement with that added to the B12, I will post again. I hope this might help others. It hasn't cured it, but it has helped.
