Possible Lupus Diagnosis, But Symptoms Don't Match?

In the process of being diagnosed with Lupus based on my blood work(positive for anti-dsdna) but it seems like my symptoms don't match or could be caused by something else. I have been sick with upper respiratory infections on and off since September. Usually starts with a sore throat but turns into sinus congestion and a runny/stuffy nose that just won't go away. It feels like my head is constantly in a fog. I've lost my voice 3 times in the span of 5 months. The only thing that's helps a bit is prednisone but even that doesn't knock it out fully. Does this sound like a lupus flare? I know it does get worse after I've been in the sun.
