Are you currently suffering from nerve injury? I had one last year from a dental implant placed on lower back tooth that hit my nerve. I can tell you that it is 99% healed and yes I took complex B vitamin and B12 that I purchased from walgreens. so whatever the dose was I think they helped a lot. I really noticed a huge improvement around 6 weeks post injury, but it did take about 3 months to feel completely normal again
