Hi & welcome. A facial rash isn't *necessarily* a lupus rash. To determine if a rash is lupus-specific, skin biopsy with immunofluorescent stain tests are often done. Actually, biopsies might not be done readily for *facial* rashes, given the cosmestic considerations? I hope people who've had facial rashes chip in soon.
When you correlate facial rashes to sun AND to other symptoms, like you write, lupus does come to my mind, too, but I'm just a patient, of course.
I had some neuro-like things. I'd sometimes misstep, then teeter/fall. Sit down suddenly, like my legs had given out. Panic attacks that shocked me, because while I wasn't a daredevil, I wasn't a nervous type, either. (Episodes occurred on bridges, planes & subways.) Migraines (ugh). Weird tingling up & down my arms & legs, like little critters flitting back & forth.
My sun problems came on gradually. First, the fatigue you describe. Next, livedo reticularis (lacelike mottling under the skin, a sign of vascular disruption). Then rashes: red rings, on arms & back, that didn't hurt, itch, scar or depigment. It took years but these lesions were finally diagnosed as a less well-known lupus rash called SCLE (subacute cutaneous lupus erythematosus).
Many people in the SCLE "subset" meet the criteria for systemic lupus, but are thought to be less likely to have the toughest problems (brain & kidneys). Most in this gorup test positive for anti-Ro (I did)---whereas I *think* people with lupus malar rashes are more likely to test positive for anti-ds-DNA (and maybe some other autoantibodies, too, I'm not sure).
Anyway, I hope you keep posting. We're good company (I think so, anyway
), and have had a wide variety of things happen. I'm glad you found us. Bye for now, with best wishes, Vee
