Welcome to the forum Kota,
If you get the rash again take a picture so you can show the doctor. A malar rash is not necessarily lupus but it will count as one criterea for diagnoses. If you look at the bottom of my signature there is a link for "4 of 11 criterea" for diagnoses. If you click it, you'll find a list of 11 criterea . . . the doctor needs to document 4 of them to consider a lupus diagnoses.
Lupus can be very difficult to diagnose so you'll need to keep a symptom journal which will help the doctor to figure things outs. There are also some great tips from the members here contained in one of the posts in "Lupus Resources" . . . link in my signature.
Learn all you can and you'll be able to help keep notes to help your doctor.
Sorry its so complicated. . . welcome to the forum!!
