"Hey" Laurianna, and welcome to WHL forum. Like Nicole suggests, you could call your gp or pcp, and aske their advice. They might have suggestion to get you by until your rheumy appointment. You might also be careful of flourescent lighting. If it's unfiltered, it can cause some of us issues. Hope you get to feeling better. One thing about the blood work, a "positive" test doesn't necessarily have to mean lupus. It might be something "simple", or not so long-term that you'd have to deal with.
