Lupus itself does not cause the purple hands. But Raynaud's syndrome does cause it and Raynaud's often occurs in overlap with lupus. Raynaud's is an autoimmune disorder that causes the nerves that control the capillaries in the extremities to contract inappropriately when exposed to chilly temperatures or stress. http://www.raynauds.org/
