Question: I am getting concerned the more research I do. Originally, I was looking into pleurisy, I think I have it again. The last time was a few years ago. I came across lupus. In browsing symptoms, I became concerned. First, the pleurisy. I have had instances of the blue and white finger and toes, plus blue arms, primarily elbows. Always been on the low iron side. Pale, so I thought that's the reason for brusing, I don't even know what causes most bruises. Could this be lupus, and when I finally get to the doc. To have the pleurisy checked, should I ask to be tested?
