Within the distribution of the involved branches of the trigeminal nerve, there is often one or more special sensitive areas of the skin that can trigger pain with slight touch, such areas are called trigger points also known as trigger points. The trigger point its range is more limited, mostly concentrated in the paranasal area, upper and lower lips, upper and lower gums, cheeks, eyebrows, etc. Common stimuli in daily life, such as talking, eating, coughing, washing face, brushing teeth, yawning, and even head movement may trigger the pain. Therefore, patients are extremely fearful and are very careful about their actions. The duration of pain attacks in trigeminal neuralgia usually varies from a few seconds to 1-2 minutes. At the beginning of the disease, the number of attacks is small and the intervals are long. There is no discomfort during the interval (except in severe cases where there is a persistent mild dull pain during the interval), and after a period of time there may be another sudden attack. The intervals may vary from a few minutes to a few hours. As the disease progresses, the pain attacks become more frequent, the intervals become shorter, and the pain becomes more severe. In severe cases, the attacks can occur several times a minute, usually only during the day, and the attacks are lighter or stop at night, but in severe cases, the attacks can also occur at night and last all day. Patients with severe disease may have painful attacks at night, which may last all day. They may not be able to sleep overnight due to painful attacks, or they may wake up with pain after going to sleep. The course of the disease may be cyclical, with each attack lasting from several weeks to several months, after which the symptoms may gradually decrease and disappear on their own, or remit significantly (from several days to several years). During this remission period, the patient often does not have further attacks, but after some time, the severe pain recurs again, with little chance of recovery on its own, but more and more frequent, and the pain level increases, but the disease is not directly life-threatening. According to the observation of scholars, it seems to be related to the climate, generally in the spring and winter season, and some people observe that the pain attacks have a great relationship with emotions, such as when nervousness, emotional instability, and impatience are easy to develop. First of all, if you are confirmed to have trigeminal neuralgia and the pain is unbearable, you should think of pain relief first. The most commonly used medication is carbamazepine, either domestic or imported (Deltodine). The vast majority of patients will get relief after taking the medication. Of course there are side effects to the medication, such as dizziness, rash, etc. If you cannot tolerate these side effects, you can also try oxcarbazepine, which has relatively few side effects. Other medications that can relieve pain include gabapentin. However, medication only provides temporary pain relief, not a cure. If you have had the disease long enough, say a year or more, and the efficacy of the medication is waning, then surgery may be considered. The preferred method of surgical treatment is microvascular decompression surgery, which can completely cure trigeminal neuralgia and has a very low recurrence rate. The safety of the surgery is also relatively high. There is no numbness in the face after surgery. Of course, the surgery needs to be performed under general anesthesia, so there are certain requirements for the patient’s physical condition. If your physical condition is not suitable for this surgery, then you can consider radiofrequency treatment, the so-called radiofrequency treatment is to use high temperature to destroy the trigeminal nerve semilunar node, this surgical method, relatively safe, can be done under local anesthesia. However, the numbness of the face will remain after the operation. The recurrence rate is higher compared to microvascular decompression surgery. However, it is suitable for people who are older and in poor physical condition.
