Carpal tunnel syndrome is caused by the compression of the median nerve at the carpal tunnel, resulting in hand numbness. The drugs available are limited. The drugs available are the following: one is neurotrophic drugs, the most commonly used is mecobalamin, and the other is anti-inflammatory and analgesic drugs, including diclofenac sodium, celecoxib, meloxicam, etc. The third type is to take traditional Chinese medicine decoction or proprietary Chinese medicine to promote blood circulation and remove blood stasis, relax channels and activate collaterals. If the symptoms of hand anesthesia are not alleviated after rest and oral medication, the nerve electromyography should be carried out as soon as possible to determine that the nerve compression site is at the carpal tunnel, and then the transverse ligament of the carpal tunnel with hyperplasia and compression of the median nerve should be cut by surgery. At the same time, the median nerve is released by adventitia, and the numbness of the hand can be alleviated quickly after the operation. The therapeutic effect is relatively good.
