I think Lynn and Joy both gave you great advice. I know it's hard to wait on seeing the Doctor and then getting the results back. What I'm hearing you say though is overall you feel pretty good and I would ay that A VERY GOOD THING.
Normally, if a person has lupus they are having problems and feel poorly. Many years back when you'd hear someone had lupus everyone thought it was a death sentence. Today, however that's not the case there are medications to treat patients and patients are living full productive lives. Is that to say there are no folks who are really sick, not there are plenty that are very very ill. Overall, though lupus can be treated and you just have to adjust to a new way of life.
I hope your appointment and tests go well. Keep us posted on what the studies showed. Oh one more thing you mentioned about being so tired and needing naps, have you ever had a sleep study? It's possible you may have sleep apnea. That will cause terrible fatigue, and can make you feel sick. It might be worth mentioning to the Dr especially if you snore when you sleep.
