### Human:\ncan my trigeminal neuralgia pain radiate down my arm to the tip of my thumb? . i have had trigeminal neuralgia for years. taking anticonvulsant meds has helped my pain but i am curious if the lightning bolt pain can radiate down to the tip of my thumb.\n\n### Assistant: no. the trigeminal nerve does not go down you arm or to your hand. the nerve that services this area comes from your neck (cervical spine).
