What exactly brings on the butterfly rash? Is it actually a rash of bumps or just red splotches? I've not be diagnosed with Lupus. I have Sjogren's and RA. Been having a flare recently and having hot flashes. One day while out in a hot warehouse my face became very red in the same shape as the butterfly rash I've seen photos of. It stayed for a few days and then lightened up. It's back this morning and I don't know why. Is this possible with Sjogren's or a symptom of Lupus?
