I am having a severe flare up with my trigeminal neurolgia. My Dr., has increased my gabapentin meds from 600mg a day, to 1,800 a day (gradually) I ve taken 900mg for the last few days and it doesn t seem to be helping the nerve pain yet. Additionally, I ve just had similar nerve pain, come on suddenly (sitting at my desk) stemming from my groin all the way down the the back side of my leg. This is not a quick stabbing electric jolt pain like I have in my head, its solid pain, with the intensity increasing every few minutes. Its lasted for almost an hour. I am afraid to walk for fear of falling down. Is there a connection between the trigeminal nerve pain and the sudden, severe nerve pain in my leg?
