Nerve block is a treatment that uses anesthesia to relieve the pain of neuralgia and joint pain. The anesthesia varies depending on the area and symptoms, such as local anesthesia or steroid-containing anesthesia. It not only provides temporary pain relief, but also eliminates secondary pain caused by muscle tension, constriction of blood vessels, etc., and the effect can be sustained even after the anesthesia wears off. There are various types of nerve blocks, but at our clinic, we perform nerve root blocks, plexus blocks, stellate ganglion blocks, and peripheral nerve blocks.
