neuropathic pain
"I was diagnose with TN (Trigeminal Neuroglia) a debilitating pain disorder/disease.  The pain started on the left side of my face, temple then traveled down to my left eye and the worse pain of all was the feeling of nerve pain throughout my gums and teeth.  I wanted the dentist to removed them but it wasn't dental problem.  I have 3 blood vessels from the brain laying on  Trigeminal Nerve, the pain was like nothing I've experience.  I literally could commit murder. 
I've been on these meds since the middle of December and it took 2 weeks to finally kick in and I couldn't be happier.  Side affects works different with everyone guess.  I've heard horror stories. With me it's a bit of drowsiness thank goodness! Good luck all."
