Regarding the symptoms of trigeminal neuralgia, there is a very typical symptom, which is the issue of trigger points. A trigger point is a specific spot on the face, which varies for each person. Once this spot is touched, it immediately triggers the pain of trigeminal neuralgia. The nature of trigeminal neuralgia pain is often like cutting or stabbing pain, and the duration varies. If the condition is mild, the initial attack may only last a few seconds, but if the condition gradually worsens without significant improvement, the pain can even last for several minutes. This pain significantly impacts patients, sometimes triggering pain during activities such as brushing teeth, rinsing the mouth, or chewing hard food. Early treatment is essential to mitigate this pain.
