Does anyone experience sensitivity with extreme temperatures or effects from adjusting between different temps? I do not adapt well to winter weather and can't tolerate being out in it very long without becoming chilled and tense. My feet still turn purple when they get too cold and last year I developed a bad case of Chilblains. We've recently had a heat wave and when being outside, sitting in my yard to feel the sun, I developed a heat rash of itchy, sore blisters. The slightest touch to this area feels like sandpaper rubbing me. I have needed to stay in shade or in air conditioning (which can also chill me). The rash areas are hands, arms and legs. Being in the shade has not been enough, I need to not be exposed to heat. Also, if I'm warm and the slightest breeze blows, I get goose bumps. My body doesn't acclimate to temperature changes in a normal way. I've never discussed this with my Neurologist but, research tells me it's most likely from my SFN (autonomic neuropathy) or perhaps from medications. Any thoughts?
