10 Signs of Lupus

7. Raynaud's Phenomenon

Raynaud's phenomenon is often associated with lupus. This disorder causes the constriction of small blood vessels in localized areas like the fingers, toes, and the tip of the nose. As a consequence, these body parts change color when exposed to cold or stress. They may turn white, blue, or grey and then red as the area warms up again. This symptom does not necessarily indicate lupus, as many conditions can cause Raynaud's phenomenon, including thyroid and blood disorders and pulmonary hypertension.
