Imagine shocks radiating across your cheek, a knife cutting into your skin or the feeling of hot coal burning your face, but not being able to find relief from the pain for months, or even years.

Nikki Samuel is one of those people. Her goal is to educate others about the disease, as well as let people know about the first International Trigeminal Neuralgia Awareness Day on October 7. Dozens of buildings and structures across the world are lighting up teal for the day.
"If we know that somebody, somewhere is looking for a cure an
