Trigeminal neuralgia is a very painful disease. Oral carbamazepine (or gabapentin) is the first choice of treatment. If the pain can be controlled and there are no side effects such as drowsiness and dizziness, carbamazepine can be applied for maintenance, but liver function, kidney function and blood tests should be checked regularly to see if there is any negative impact on the body, and if there is, the drug should be discontinued. If the medication is not well controlled, or if the side effects are not tolerated, radiofrequency destruction of the meningeal ganglion can be considered. The operation is relatively simple and the cost is not high, generally within 5,000 yuan.
