Is trigeminal neuralgia caused by an inflammation of the blood vessel?

Doctor's Answers 1

Trigeminal neuralgia itself is caused by compression, as the vessel rubs against the nerve and that damages the nerve as it rubs more and more. It is not a blood vessel problem but rather the compression and rubbing on the nerve that causes the damage.

It can be caused by trauma or can occur spontaneously. Although it looks alarming, it almost always benign and the blood will absorb spontaneously within two weeks.
