@neuroproblem yes, < 1% of the population gets scheuermann's. i guess i was one of the lucky few. why do you think the PN is caused by the kyphosis or the surgery? i didn't have signs of PN for years after my surgery for kyphosis. it wasn't until i had my surgery for the stenosis in my neck that i did. as far as the b6, all i was taking was a simple multivitamin. its strange to think that would cause my PN.

@englishdave i remember reading about mad cow potentially being in sphingolin. thanks for reminding me. i think i will just take the inosine for now, but i'll consult my neuro before i start taking it.
