@gba - When I first read your post, I immediately thought "no and no"...but then, it's more than that. I always enjoy posts by Chris Trout who has the ability to look at things from experience and various perspectives. The stem cell point is something that I feel has to be given a lot of consideration. Personally....I doubt anything can be curable until it is first treatable. As it stands, only about 8% of us have PN. Covid, cancer, heart disease and other things that can take our lives have taken center stage. And, think about this, when you tell someone, you have peripheral neuropathy, most people never heard of it and if they did, they got it wrong. First, figure out how to regenerate never damage and through treatment, you might just find the cure. So, I will revise my initial reaction to: Hopeful and possible. Thanks for bringing this up! Ed
