Trigeminal neuralgia is characterized by brief, lancinating, electrical shock/light pain with free intervals when the patient is completely asymptomatic. Attacks may occur and terminate abruptly, although the patient may experience background, burning pain between �shocks�. The pain attacks are unilateral and usually triggered by chewing. Most patients are over 50 years of age, when it occurs in a young patient, multiple sclerosis must be conceded.
The diagnosis is made by taking a detailed history and physical of the patient. A CT Scan of the face may be required to rule out any tumor.
