I am in the same boat. I also have Reynauds which can cause my fingers and toes to go completely numb and white. I'm convinced this symptom could be a part of what LD is. Also, during the first few years of LD, I could not stand cold, not even from an air-conditioner. I felt like the cold was stabbing through me like a knife. I'm a little better now, but I always wear a sweatjacket when I go out (how rare is that???) because I never know what the temperature will be at various places.
I also can't handle hot weather (and I live in FL). I cannot stop sweating. Even when I come back indoors, I continue to sweat for a few hours..... this disease sucks wind.
