I suffer from sever trigeminal neuropathy on the left side of the face; Dosage of Neurontin at 1200 mg per day takes away some of the pain, but not the severest pain between the mouth and lip which makes it increasingly difficult to talk during the day. Alll suggestions are welcome. Has anyone had botox injections for trigeminal neurpathy? The face is throbbing as I write and thanks to all for any help. I am at my wit's end and do not know what to do. More Neurontin is an option but as it hasn't doesn't anything for the severest pain I doubt that more if the sale will do. Best to all, Buffy
