I would not see an immunologist unless you had a specific reason for doing so. A good friend is an immunologist/allergist and has autoimmune diseases but sees a rheumatologist, not someone in her specialty. Rheumies are the doctors who are best trained and prepared to diagnose and treat most autoimmune diseases like lupus.

Remain Optimistic and you can overcome.
