The trigeminal nerve is located on the human face, and trigeminal neuralgia is a common neurological disorder. The most prominent symptom of this disorder is pain that feels like needle pricks or knife cuts. This pain usually occurs very suddenly and is extremely intense. When the pain occurs, patients cannot perform any movements related to the face, severely affecting their quality of life. Moreover, sometimes even a minor movement can trigger repeated episodes of pain, placing the patient in constant severe discomfort. Therefore, trigeminal neuralgia is also referred to as "the worst pain in the world."
