What tests can help diagnose trigeminal neuralgia?

No one specific test can confirm you have trigeminal neuralgia. Often, the diagnosis is made by ruling out other possible causes of your pain. Your doctor may try to pinpoint the cause by asking you questions about your symptoms and medical history. You may be checked for other things that could be causing your pain, such as jaw, sinus or tooth problems.

A type of brain scan called magnetic resonance imaging (MRI) may be done to see if a blood vessel is pressing against your trigeminal nerve. An MRI can also look for signs of a tumor or other problems.
