A patient came to see me a few days ago. In the past, she had always thought this pain was was a toothache and had been seen at her old home dentist. Time after time, one after another, she actually had all the teeth on the side of the pain pulled out. It was only during this visit that she found out that she had trigeminal neuralgia. In order to avoid the repeated occurrence of such misjudgment, I would like to introduce the clinical manifestations of trigeminal neuralgia, hoping to help some patients to “get the right number”. Typical trigeminal neuralgia manifestations are: 1, common in middle and old age, that is, the onset of the disease starts after 40-50 years old. 2, the nature of the pain: there is like a knife cut, electric shock-like, tear-like, sharp and severe pain, and toothache, common stomach pain is obviously different, the pain is called dull pain, and the location of the pain is not very precise. The location of sharp pain is very precise after the injury of needles, knives, etc. 3, pain location: confined to the facial trigeminal nerve distribution area, bounded by the midline of the nose, limited to one side of the attack, radiating along a branch of the trigeminal nerve distribution area, not more than the midline, can be 1, 2, 3 branches alone pain, but also adjacent to two branches, such as 1 + 2, 2 + 3 or 1 + 2 + 3 are attacked, there will not be 1 + 3 branches of this situation. 4, the type of seizure: pain occurs as a sudden, lasting a few seconds to a few minutes, there is no obvious pattern, can be a good long time without, can also be a day seizure hundreds of times, often with the passage of time, the seizure more and more frequent. 5. The most characteristic manifestation: trigger point, also called trigger point. When patients brush their teeth, eat, drink or speak, or touch their cheeks, upper and lower lips, nose and other parts of the body will cause painful flare-ups, which is called the trigger point, and is also the most characteristic manifestation of trigeminal neuralgia that distinguishes it from toothache, temporomandibular joint pain and other diseases. 6. Typical trigeminal neuralgia responds well to treatment with carbamazepine, at least early pain relief is also a major feature. Atypical trigeminal neuralgia manifests as follows: some patients have typical attacks in the early stage, and later, because they have experienced various kinds of treatment (such as local acupuncture, closure, physiotherapy, etc.), the above symptoms are not obvious, such as the site of pain, there is no obvious performance on which one, the nature of pain also becomes persistent and less sharp, the trigger point is also blurred, and the effect of carbamazepine treatment is not good. There are also patients who are atypical to begin with, including the age of onset (starting in their 20s), the location, nature and type of pain episodes, not to mention the absence of a clear trigger point. Finally, the general public is reminded that seeing a doctor cannot be taken literally, nor can they simply diagnose and treat themselves from newspapers or the Internet. We are only hoping for a basic understanding through some scientific education on disease knowledge, which cannot be completely right, and specific diagnosis and treatment requires a hospital visit.
