Trigeminal Neuralgia

	If in fact it is trigeminal neuralgia (tic doloreaux), there is 
no "trigger" in the usual sense of that word. Ergo, idiopathic. (i know 
that isn't really helpful.) 
	"Recurrence" is not the correct question. Medication (almost 
always carbemazepine/Tegretol as first choice) increases peripheral 
threshold so that the paroxysms of pain are not perceived; thus, the 
condition is constant; the treatment is symptomatic.
	Tic is uncommon at her age. Rarely it can be a manifestation of 
incipient multiuple sclerosis (common in her age group), sometimes 
antedating clinical presentation by up to 5 years.
	An MRI in idiopathic tic is expected to be normal.
