Trigeminal neuralgia (try-JEM-ih-nul nu-RAL-juh) is a condition that causes intense pain similar to an electric shock on one side of the face. It affects the trigeminal nerve, which carries signals or sensation from the face to the brain.
It’s most common in women aged over 50.
Symptoms range from mild to severe facial pain, often triggered by chewing, speaking or brushing the teeth, or applying makeup may trigger a jolt of pain.
