What is the cure for trigeminal neuralgia?

Depends which Dr.: Many drs rely only on pain meds to control trigeminal neuralgia.Some use surgery to cushion a nerve.More recently (though little known) neuroprolotherapy has been found to help.It consists of injections of 5% glucose near the affected nerve(s) which calms it.I have yet to see if effect is permanent, but my pts like it.Also osteopathic cranial manipulation helps some.So, depends on Dr's training.

Cure for TN: There is no cure for TN. Current state of the art dictates that all patients should be treated initially with medication. But if a patient becomes refractory to medical management or develops serious side effects to medication, surgical intervention should be considered.

Try carbamazepine?: Diagnosis is made in conjunction with your DR, based on typical symtpoms. First-line treatment is with Carbamazepine a type of anti-epileptic that can abolish symptoms in many cases, the effect does diminish over time. If symptoms do not respond diagnosis should be re-visited, consideration given to MRI scan and surgical intervention. http://patient.info/health/trigeminal-neuralgia-leaflet
