You are absolutely right! You should not have to suffer from symptoms because you have not been diagnosed. If your doctor feels that you are suffering from some form of auto-immune or connective tissue disorder, the treatments are essentially the same for the symptoms you describe.
Perhaps you should ask (or insist that) your doctor prescribe treatment for your symptoms while she is testing you for diagnosis.
It will be difficult for you to compare your symptoms with anyone else because no two persons suffer from their Lupus symptoms in the same way. Keep a record of your symptoms, when they occur, how long they last and the circumstances under which they occurred. This will help your doctor greatly in attempting to diagnose your symptoms.
I wish you the very best!
Peace and Blessings
