So true about even the side effects of the side effects being different. In the first few months of pn, as well as numbness, I had significant pain, particularly in my toes. But that abated, so now I have limited feeling in lots of patches, can't tuck my toes and my feet range from almost normal to walking on dunlopillo with multiple pairs of socks inbetween. But no pain or extremes of temperatures. And it is improving - speed of a glacier, but improvement is improvement. 6 years though......
