I am sorry your doctors have not done much about the PN. Ketamine cream also has some relief, maybe better than the patches. Lidocane patches are fine until you go to pull them off!,
There has been a lot said about the drugs that can cause PN. I have no doubt that is what did it for me. I go to a integrated physician, who has done much to get me in a better place.
You have to find a doctor willing to think outside the box to help you. I am here to listen anytime. ginnie
