I'm glad someone is showing studies about this online. I have something like that. When I've been at work under the fluorescent lights or outside I get a rash across my cheeks, chin & forehead. People think I've been tanning & burned. I know I've been exposed too much when my eyelids start twitching & my brain stops working. I'll be walking thru Wal-Mart with a list in my hand & not be able to read it or remember what I just read. Then I get the flush, my cheeks feel numb & tingly at the same time & the next couple days my joints scream & my fibromyalgia (the only thing they can find wrong with me) flares up worse. I've been tested for autoimmune & lupus twice in the last year but nothing showed. I've read it takes up to 3 yrs sometimes for tests to pick it up. I don't have the purple eyelids and knuckles like they speak of here but it's related. Any ideas? I know there are more autoimmune diseases that flare up from UV rays but I'm not finding them online.
