There are so many different skin rashes with Lupus and the ones you describe do sound like one of the rashes that are common with Lupus. Here are some websites that will give you explanations about the many skin rashes that we suffer from:
As has been mentioned, each persons Lupus is specific to them, the flare-ups, manifestations of the disease, and symptoms are all individual. Also, our flare-up this month can be totally different next month (different triggers, different symptoms, different organs).
Most of us are extremely sensitive to sunlight and to fluorescent lighting (like the type used in Walmart). That is why it is suggested that we wear hats and sunglasses whenever we go to a large department store or grocery store. These lights, alone, can send us into a flare-up. So you must protect yourself from sunlight and fluorescent lighting.
Please read the sticky in "Newly Diagnosed" about testing for Lupus. If, after that, you still have questions, I will be more than happy to try to find answers for you.
Peace and Blessings
Look For The Good and Praise It!
