Help with canker sores ar cold sores and increased nerve pain

I get what I am pretty sure are canker sores inside the cheek at the way top where the nerve pain is, then they will sometime spread inside my lip or center cheek. During these times the nerve pain is greater. I am not sure if its from the stress of having the TN or a virus? Is the increased nerve pain/stress causing the sores or the sores causing the pain. Where they are has to be canker sores right? All I have read about here is cold sores and Post herpetic neuralgia. It has happened a few times coinciding with the TN pain flare ups. My neuro brushes it off. Anyone have any feedback?

Teri,

I take 3 to 5 mg of folic acid everyday to help prevent the canker sores as they are also connected to my arthritis, rheumatologist prescribed them. I've also heard that B vitamins can help, but I do not have experience with these.

Hope you find relief, they can be very painful!
