does nerve block injection work
A nerve block is an injection to decrease inflammation or turn off a pain signal in a specific area. Imaging guidance may be used to place the needle in the right location for maximum benefit.he effects of the injection are usually immediate. It only takes a short time for the medication to achieve pain relief. However, nerve blocks are only a temporary fixâthey typically last for up to one or two weeks and then wear off as they are absorbed by your body.
