Could ba a symptom of raynaud's phenomenon... Do your hands ever turn like ghostly white? Do you notice it more when you're stressed or when you are cold?
I notice that since I've been sick, I am cold more often, too... Not just my hands and feet from the Raynaud's, but my whole body... Either I am freezing or I am burning up.... No comfort zone anymore.... I think that Lupus makes you cold and the meds are what make me hot... LOL!
Let us know what the dr. says!
