Hey Veronica,
Having a sensitivity to fluorescent lights is classic Lupus. I don't know of any Lupus patient that isn't sensitive to those poisonous lights. Change those fluorescents back to the old incandescents. They're really bad for us... One hour under fluorescent lighting is equal to spending 15 minutes in direct sunlight. Terrible!!!!
Definitely bring this up with your rheumy and push for a repeat of Lupus panel tests. Make your rheumy very aware that you are serious about finding what's wrong. Make them listen!
Good luck, keep us posted,
Ginny
