Facial Pain (Trigeminal Neuralgia)

Compression of the trigeminal nerve by a blood vessel at the base of the brain may cause trigeminal neuralgia. Tumour and multiple sclerosis are other important causes. Unfortunately, the cause of trigeminal neuralgia is unknown and there is no disease involving the trigeminal nerve or the central nervous system. Thus controlling the pain is the mainstay of treatment. 

You should see a doctor to confirm the diagnosis. Your doctor will conduct an interview and physical examination. He may ask you specific questions regarding your pain, including onset, nature and triggering factors. He may also arrange for you to have a magnetic resonance imaging (MRI) of the brain. 

Your doctor may also refer you to a neurosurgeon if deemed necessary.
