Hello franceunderpants,
I wonder if you have seen a neuro doc? and sure it could be related to your earlier neuropathy or many other things also. Too T.N. pain is not always shooting and sudden ... I know of people who have started with just a little "weird" feeling and then it has slowly grown into the bigger pains as decribed . some go into "remission" and have no pain and then suddenly it comes back sometimes worse then before their remission. I would denfinatly mention your thoughts, symptoms and questions to your genral practions doctor and maybe if they think it is a good idea you can be refered to a neuro. write down all the things you want to ask or say to your doctor and go see them thats is a great place to start.
I wish the best for you and hope you keep us posted on how things go for you.
Peace
BMW
