Well it s true but not in all cases. You can get T.N. after having chicken pox ..shingles they are both forms of herpies and are known to be the cause of some peoples T.N. .

I would NOT say it is the cause for all t.n. and more often there are other reason for the cause of T.N. A.T.N. A.D. etc...

My thoughts on Micro electric current therapy I am not sure what that is but I know first hand that eletrical stimulation is very helpful.. I have a neuro stim implanted which I think is NOT the same as Micro electric current therapy but may be along the same lines . I will have to "scooby doo" it and see what reasearch pulls up for me.
Thanks for posting this.
