I have suffered from TN for 2 years and it's an incredibly horrible experience. I have tried all types of prescriptions for it. I am not a medical professional in any way, but I personally have found that i have to change prescriptions every so often to keep it under control. I currently take Lamictal for it. Pain medications are if no benefit. I have a former teacher who had surgery and has been pain free for 6 years! There is hope even though it's hard to see in the midst of the pain. If you ever need to talk or vent send me a message!
