Caroline, others on this forum will speak more directly about your symptoms, but it certainly sounds like your physician has a reason to run tests. There are lots of diseases that look like lupus, so it's a tough disease to diagnose. Marycain and Saysusie will probably weigh in here with some good information for you. In the meantime, I'll keep you in my prayers, Caroline. Know that you are not alone. We're here for you.
