Michael - I do agree with your comments and I've been thinking for a few years why hasn't the medical field found out a way to fix this. Not try this medication or that medication. Yes, some help...for a while...and I'm glad that we have those meds but come up with the solution. No easy answer but my belief is that it has to do with money spent on research and priorities. When my neurologist told me that I would die with this but NOT from it, I knew then that PN was not on the front burner for a cure. Like many, I'm idiopathic. So, it looks like it's going to remain a mystery for a while.
