Good morning, kathryn+2. I don't think you said WHICH type of lupus you've been Dx'ed with, e.g., SLE vs. SCLE vs. DLE (etc.). Here's something I was told by both drs. who Dx'ed me with SCLE: that rashes can "cross subsets". What that means: in addition to the rash(es) most associated with the form of lupus you have, you can get OTHER lupus rashes & other non-lupus rashes, too.
I'd had nonscarring rashes on my arms & torso, so after Dx, I was covering up pretty well (long sleeves & trousers, sunblock, etc.), but I still wore a SUN VISOR, which left my scalp exposed to sun. It was gently [
ahem!] pointed out to me that I could get scarring "discoid" lesions on my scalp, which can cause permanent scarring & hair loss.
Immediately, on the way home from that appt., I bought a couple of serious hats with broad brims. And, my luck, I eventually did get one scarring lesion, on my face.
Someone here sometimes says, "The sun is our enemy." This applies not just to skin concerns, but also in the broader sense of the wide array of systemic problems lupus can cause, some of which are truly profound.
I must sound like a nag, but at least you can mull these things over. Plus, photosensitivity varies: I'm VERY, but you may not be. Anyway, sending you best wishes & hoping your sunburn calms down quickly, Vee
