There is no cure for PN. If it is a result of another ailment or disease, treating one probably will have little or no effect on the other. You can be cured of a 'curable' problem, but if it has created nerve damage or nerve death, you still will be stuck with PN- chronic and at this point incurable. PN problems have been known to subside with treatment, or surgery- of nerve compression, but that's another story. So is supplements, and meds, to promote nerve growth.
