Trigeminal neuralgia is a condition characterized by intermittent pain, usually on one side of the face, somewhere along the distribution of the trigeminal nerve (ear to eye, nose and jaw). Sometimes there's a headache with it (same side), sometimes not.
If there are no other symptoms and it goes away for months at a time, and the pain can be largely controlled by avoiding triggers and taking ibuprophen, is it really necessary to have imaging studies done to rule out compression of the nerve or the small chance that it's the first sign of MS?
If such a condition has been occurring intermittently for years, if it was caused by a compression of the nerve, wouldn't there be definitive symptoms after such a period of time? If it were MS, would other signs have manifested themselves during a period of years?
