Incomplete lupus?: Your physician may be considering incomplete lupus, in which some features are present but there are not enough to establish the diagnosis. Rheumatology is curious in that there are a huge number of labs, but the diagnosis is usually made on history and physical exam. Incomplete lupus needs to be followed closely as there may actually be some other illness. Good luck.

Lupus most likely: You are describing a complex of symptoms and findings consistent with lupus. The positive ana, rash and joint pain gives you a 75% likelihood fo having lupus. All these symptoms are responsive to prednisone. Looking for other possible areas of involvement such as blood or kidney abnormalities is important. See a rheumatologist.
