AGGH! "trigeminal neuralgia" I had that for about 6 months about 10 years ago. Horrible. Like pressing thumb tacks thru your skin into cheek bones. It spread to all kinds of neurological weirdness: other puncture pains, numbness in hands/legs, inability to swallow properly, inability to start/stop pee properly. My doctor thought I was in the beginning of multiple sclerosis. That was one of the worst times of my life. I looked at every person on crutches or wheelchair and just knew I would be there soon. Then it slowly got 99% better. Today there are tiny recurrances, but I don't worry about it lasting forever.

Some here mentioned swallowing problems recently. I don't recall who and wanted to reply. You should definately see a doctor about this. It can be an early sign of MS or other perhaps a neuro toxin.
