Trigeminal neuralgia is a chronic pain disorder affecting the trigeminal nerve, the primary sensory nerve responsible for facial sensation. It is characterized by sudden, severe, electric shock-like episodes of facial pain that may be triggered by everyday activities such as talking, chewing, brushing the teeth, or lightly touching the face. Although it may be mistaken for facial paralysis, trigeminal neuralgia is a distinct neurological condition that primarily causes pain rather than muscle weakness. Early diagnosis and individualized treatment are important to help control symptoms and improve quality of life.
