Trigeminal neuralgia is very common in clinical practice and its pain is relatively severe. Most cases exhibit a cutting-like or electric shock-like pain, and sometimes burning pain can also occur. The pain process is often very painful, but once the nature of the pain disappears, there are basically no obvious clinical symptoms during the intermission period. Therefore, in practical work and learning, it is essential to avoid triggering trigeminal neuralgia, such as by reducing exposure to cold and hunger, and minimizing chewing hard foods, all of which can reduce the occurrence of trigeminal neuralgia. However, the most important point is that if trigeminal neuralgia persists, it is crucial to visit a hospital for appropriate diagnosis and treatment in order to achieve a relatively good therapeutic effect and reduce the patient's suffering.
