Trigeminal neuralgia is one of the most common, stubborn, and excruciatingly painful diseases, known by patients as the "world's most severe pain." The intensity of the pain during an episode can surpass even that of childbirth. When the pain is severe, patients dare not speak, eat, or sleep, causing immense suffering in their lives. In extreme cases, the unbearable pain leads to suicidal thoughts. Therefore, trigeminal neuralgia is also referred to as the "non-lethal cancer," a serious neurological disorder.
