I have radial nerve pain and right now on physical therapy. My doctor said that if PT doesn’t help that the next thing is a nerve blocker. How is this done. I sounds very painful. Can putting the needle into the nerve cause more damage and pain to the nerve?
Before having a nerve block, one has to diagnose the cause of the pain. You are correct that injection into the nerve can worsen the pain. However, injections are done usually close to the nerve and not into it. But before injecting the nerve one has to know what the pathology (problem) is. Without a proper prior diagnosis, nerve block treatment may not be appropriate.
