Saw my doctor the other day. He wants a better MRI of my neck, due to pinched nerve issues. As far as the TN, he said he thinks it’s due to a viral infection, no longer in my system by leaving behind damage. One of the herpes strains, varicella zoster (chicken pox). I’ve been doing research, but haven’t found much that’s recent.

That sounds like Post Herpetic Neuralgia. The good news is that they can treat the virus and help keep your TN pain to a minimum.
