I have Trigeminal Neuralgia in the left side of my face. I started out taking 2 Gabapentin 300mg pills daily now up to 4 daily. It's been 6 days and still no relief. This is the most debilitating pain I have ever experienced. Feels like it's being electrocuted every few minutes. Goes across that side of my face and down my jaw bone. Any help would be great, thanks.
