In brief: Trigeminal neuralgia

The presumed cause of tn is a blood vessel pressing on the trigeminal nerve as it exists the brain stem. The compression causes the wearing away of the protective coating around the nerve(myelin sheath).
Other causes include nerve damage, genetic tendency, stress is an aggravating factor. This deterioration causes the verve to send abnormal signals to the brain.

This blood vessel is typically the superior cerebellar artery that is compressing the trigeminal nerve just as it enters the brain stem. There are many other causes, and this pain could be a sign of a serious diagnosis requiring more urgent therapy. An expert medical opinion should be sought.

In brief: Compression of nerve

Compression of the trigeminal nerve root causes tn.
This can occur with abnormal blood vessels (most common) or tumors or cysts.
