“A nerve block is an injection to decrease inflammation or “turn off” a pain signal along a specific distribution of nerve. Imaging guidance may be used to place the needle in the most appropriate location for maximum benefit. A nerve block may allow a damaged nerve time to heal, provide temporary pain relief and help identify a more specific cause of pain.
This procedure requires little to no special preparation. Tell your doctor if there’s a possibility you are pregnant. Wear loose, comfortable clothing and leave jewelry at home. You may be asked to wear a gown.”
