Why is it that the periods of pain are intermittent and that there can
be long periods of remission?  If it is caused by vascular compression,
why is the pain not constantly there?

I was not asking about postherpetic pain, but rather asking if it is
possible that TN could be caused by an internal herpes simplex infection.
Since the HSV which appears as cold sores on the lips lies dormant in the 
trigeminal ganglion between attacks, why couldn't it attack the 
trigeminal nerve itself?  Could TN be cause by an internal herpes 
infection?  Is there even such a thing as an internal herpes infection?
