Hopefully you just had the flu. Or your system is out of whack from your flu? Chicken or the egg?!?
A dermatologist would have to diagnose your rash. I just went last week for a check up and asked him to do a biopsy of my malar rash just to be sure. He just laughed at me and said that he was 100% sure. They can tell right away. Mine is bad though.
Have you been in the sun? What state are you from? Mine definitely gets worse in the sun or fluorescent lighting. I also get flu-like symptoms with my flares. I usually have a temp of 101 - normal for me. This has been a late flu season, too. Hopefully you will start feeling better soon. You know that rest and fluids are essential during your flare. Why does it take so long to get in to see the rheumy?
