Sometimes it takes people years to get diagnosed, Lupus is a very difficult disease to identify. It isn't diagnosed by one clearly defined blood test, instead by having 4 of 11 symptoms.
You should probably take her advice and take plaquenil (known to help slow/inhibit the progression of Lupus) and prednisone (helps lesson the inflammation it seems is going on in your joint, and the accompanying fatigue). Sometimes we are only diagnosed by seeing if we react positively to these meds -- if not, it can be something else.
You not caring about
anything can be a sign of depression. She might be able to give you an anti-depressant as well. And sometimes the fatigue is worse because of not getting deep, restorative sleep - perhaps you need a sleep aid (also some people are sensitive to prednisone and have trouble sleeping.)
