Hi darkorchid12 .....
Although I had a vestibular schwannoma (aka acoustic neuroma), not a trigeminal schwannoma, I did have trigeminal neuralgia 20 years ago that was successfully treated through microvascular decompression at the brainstem, via retrosigmoid approach.
The 12 cranial nerves all originate at the brainstem, in very close company with each other. Therefore a schwannoma on any of them could include symptoms for the others, depending upon its size and specific location along the nerve.
Since your situation is very rare, I would search diligently for experts in specifically treating trigeminal schwannomas. Not all neurosurgeons are equally well trained in treating skull-based tumors or cranial nerve tumors.
You certainly can remain in this group, even if it does turn out to be a trigeminal schwannoma ..... there are many similarities between them.
Thoughts and prayers.
