Hello @ahendershot, welcome to Connect. I also have idiopathic small fiber peripheral neuropathy but have had it 20+ years. Mine is mostly numbness in my feet and just above the ankles. This past winter while clearing snow I stayed out a little longer than I should have and even though I had good gloves on my hands got very cold and as a result it feels like I have the start of neuropathy in the tips of a few fingers on my left hand or it's a result of frostbite.

Do you have pain with your neuropathy? I don't have any pain from it but I take supplements which has slowed the progression of the neuropathy. I posted what helps me earlier on Connect here: https://connect.mayoclinic.org/discussion/anyone-here-dealing-with-peripheral-neuropathy/?pg=42#comment-65985
