The injection containing medicine will be administered with precision, as close to the afflicted nerve as possible. We will use imaging tools to assist us in placing the needle in the most optimal position. Once the needle is injected, the medication will be delivered to the affected region. This will numb the area and reduce inflammation, and if need-be, we can deliberately damage the nerve. Doing so will stop the pain signals being sent from the nerve.
The procedure itself is done quickly, and we may ask you to stay for an extra half hour to monitor any adverse side effects. You will typically notice the effects of the nerve block instantly as the medicine provides relief in a short period of time. However, nerve blocks normally last a just few weeks before being absorbed by the body. Some individuals may require multiple treatments before experiencing long-term relief.
