It sure looks like you have something that is autoimmune...getting a lupus diagnosis has to do with the criteria and some docs will say blood tests are primary, also. (There are sticky's that are extremely informative to that point)
You know some of the symptoms sounds like Sjogrens(I am not anything medical)...I am having a workup for that...dry eyes, mouth...cavities, dry skin...etc...I even have vaginal dryness (sorry Rob or other men reading this) which is another symptom. What you will find when you are reading, is some of those could be the same for lupus, too.
So when is your next Rheumy's appt? I will be interested to know what he says.
