I can relate. I have full-body small fiber neuropathy - the bane of my existence. I also live in Minnesota and we have HUMID hot summers and horrible cold, dry winters. I've only had neuropathy for a year so I can say I've experienced every season now. Winter and summer are bad. Spring and fall was fine. This morning it was -25 and I felt like every square inch of my body was being attacked by fire ants. My raynaud's is also out of control. I don't know why it also happens inside, but I can tell you that weather extremes of humid hotness or dry coldness do make my neuropathy 1,000% worse.
