The procedure involves injection of a local anesthetic-steroid mixture in proximity to the injured nerve, decreasing the transmission of pain signals to and along the nerve. In some cases involving sensory nerves, temperature-based therapy such as cryotherapy or radiofrequency lesioning may be used as a long term pain solution. Terminal cases can call for substances such as phenol and alcohol to be utilized, providing long term relief. While any complication from this procedure is rare, there may be a risk of infection, bruising, or damage to the nerve. After the injection, any soreness can be managed by applying ice for 20 minutes two to three times a day.
