The length of pain relief after nerve block varies upon the solution that is being used or the technique that's being used. If it's a local anaesthetic, it may just last for a few hours. Then again, it may last forever, you never know. If it's a steroid injection like cortisone into the area, we typically find relief in that area for up to several months. If it's a phenol injection, it can actually kill the nerves; it may be permanent.
