If you have trigeminal neuralgia, even mild stimulation of your face — such as from brushing your teeth or putting on makeup — may trigger a jolt of excruciating pain. You may initially experience short, mild attacks. But trigeminal neuralgia can progress and cause longer, more-frequent bouts of searing pain.

The hallmark issue of Neurofibromatosis Type 2 NF2 is the bilateral growth of schwannoma bilaterally on cranial nerve 8 CN8the nerve in the brain vestibulocochlear nerve. CN8 has two branches of different function the cochlear auditory nerve branch for hearing and the vestibular nerve branch for balance. These tumors are either called acoustic neuroma AN or vestibular schwannoma VS.
