It's now 2 weeks since I had this trigeminal nerve block on the left side, they only do one side at a time. I haven't had pain in the left side of my face since I got it, so it's a success. I still have to tell pain management and see what they say this means. I know it was in part diagnostic, so if it didn't work my trigeminal nerve wasn't the source of my face pain. Apparently the trigeminal nerve is the source of my face pain, in part, so not sure what that means and not sure how long the nerve block will last. But I'm feeling very happy, this is a horrendous, debilitating issue, so to be able to block that pain is a big deal. Between this and the Lyrica I may be getting a lot more functional.
