Does anyone get a cold hand when eating, especially in the morning? I can't figure out if this related to blood sugar, circulation, cortisol, dysautonomia, or some sort of autoimmune reaction. If I eat something, sometimes but not always, in the morning, my right fingers will get really cold. I thought this may be due to some sort of hypoglycemia, but I can't figure it out. Allot of times it's just my right hands and my finger tips, but sometimes it's both and sometimes it can be the whole hands. Sometimes the warth will rush back inexplicably. It doesn't seem to happen as much at night as I'm usually warmer then, which makes me think it's cortisol related.
