Trigeminal neuralgia (and it's also known by an acronym: TN) is a rare affliction characterized by pain on the face. It's usually one half of the face or the other half of the face. Usually these episodes of pain are shock-like, they're intense, people don't know why they're experiencing this pain. They will seek medical attention and it's rare enough of a disorder that many times we don't get the diagnosis until weeks or months later. But it's an important diagnosis to make because there is good treatment for it once you identify the diagnosis correctly.
