It is well known that 95% of the causes of trigeminal neuralgia
is pressure on the trigeminal nerve
close to where it enters the brain stem (the lowest part of the brain that merges with the spinal cord
), past the Gasserian ganglion
In most cases, this pressure seems to be caused by an artery
or vein compressing the trigeminal nerve.
The pain in trigeminal neuralgia can be along any of the branches of the trigeminal nerve or anywhere along the nerve. So the new onset pain is part of the trigeminal neuralgia.
It can be confirmed if a high resolution MRI shows the abnormal structure and the if so the problem can be solved through surgery.
