I have PHN and started this discussion. PHN is high level pain. Your life is no longer yours. I'm on year 8 and the only thing that comes near to relief is a neurorectomy. I've had one and hope to get another this year. Resources for PHN in the US is zero. Insurance (most) does not cover neurorectomys and it normally takes more than one surgery. There are only four doctors in the entire US that perform the surgery in hopes of relieving pain. I have tried just about everything.
