Hi John,
You are right in the fact that dead nerves can not seek any benefit from medication. I'm speaking for those who experience nerve pain (burning, sharp shooting, tingling, numbness) so they can find relief. Most doctors do not specify nerve pain and get people on the right medications. Neuropathic pain can be controlled and patients can have relief. The more we teach each other, the more people can take control of their pain issues in the correct fadhion. I hope you can find relief for your discomfort which I know is annoying. You are blessed that it is no longer hurting.
