Trigeminal neuralgia has the notorious reputation of being the “number one pain in the world”, and although it is not life-threatening, it can be excruciatingly painful. The doctor’s diagnosis of trigeminal neuralgia is based entirely on the patient’s self-reported symptoms, and tests such as MRI are only auxiliary means of diagnosis. Therefore, an experienced doctor can make a clear diagnosis by asking the following 6 questions over the phone. In fact, one question is a diagnostic point, and the higher the compliance rate, the greater the certainty of the diagnosis. The specific questions are as follows: 1. Pain site: located within the innervation area of the trigeminal nerve. Specifically, the face, tongue, teeth, oral mucosa, nasal cavity, and external ear canal. 2, the nature of pain: often described as electric shock-like, pinprick-like or knife-like severe pain. 3. Seizure characteristics: paroxysmal, several times a day, for a few seconds each time and gradually aggravated and prolonged. Later on, it can be of continuous-burst type. 4. Trigger point: contact with specific parts can trigger painful attacks, such as brushing teeth, washing face, etc. 5.Influencing factors: exertion, excitement, cold, head position and other factors can aggravate the pain. 6.Medication: Early administration of carbamazepine is effective.
