I know our pain is caused by different things, but I would be very wary about having acupuncture for Trigeminal Nerve pain. Acupuncture dilates blood vessels, and the first acupuncturist - a Physio - I saw for neck and shoulder problems caused IMMEDIATE TN attacks as though I had taken my heart GTN spray.
The second, a Nurse Practitioner with Traditional Eastern training, I saw for a worsening of the same neck injury knew which areas to avoid - head, neck - concentrating the needles in my back and arms.
Just make sure your Dr knows your WHOLE history, complications, etc, before starting treatment.
It is nice that you seem positive about this though, keep it up.
