You may have lupus, however, the exact label is not essential for your doctors to take care of you. The treatment is geared towards your symptoms and the organs that may be affected by the auto-immune process. SLE has a wide range of clinical presentations. It would be prudent to work with your rheumatologist. Wish you good health!

Rely on your rheumatologist to diagnose lupus. There are now a variety of poorly differentiated autoimmune disorders with some exhibiting mixed features as well. Acute/ subacute conditions may interfere with ability to diagnose and changes in time may help in properly diagnosing such conditions.

You could get a second opinion by consulting a rheumatologist at the department of rheumatology at a university hospital near you. He/she may wind up by validating your rheumatologist's recommendations and conclusions.
