This is just my take. Will it be cured. Yes. At a date TBD. First breakthrough will be pain management treatment mitigating pain. Then stopping the spread. Finally reversing PN. But hey, I'm 76 yo and I was told as a 30 year old by an ENT specialist that I would not live to see damaged left auditory nerve being repaired. Like my PN, I've learned to thank medical science for amazing advances that have got me this far and then live with the rest. And thanks also to forums like this!
