@sweetie23 I have severe small fiber neuropathy (diagnosed by biopsy); the itch occurs mainly on my back. I tried Sarna lotion as recommended by dermatologist. It helps just a little. I have also tried Zyrtec since I take it in the spring and fall for allergies. I think it also helps, but the itch is maddening. I have not had it as bad this winter, so maybe you are right about heat and humidity. I do take supplements that are supposed to help neuropathy along with omega 3 from algal oil.
