Blue Fingers
A disconcerting symptom of Lupus is also known as Raynaud’s phenomenon, where an occasional restriction of blood flow to the fingers, such as during exposure to extreme cold, can cause the fingers to turn cadaverous, numb, and later, a pale blue due to the lack of properly oxygenated blood. Then, blood rapidly flows back into the extremities, turning the skin purplish and flushed. During this moment, the skin might feel hot to the touch and will even throb and tingle.
Luckily, this is one symptom of Lupus that doesn’t pose any medical threat. Raynaud’s phenomenon is visually upsetting to some, and the physical symptoms can be frustrating at times, but the extremities are not at risk of permanent damage.
