I was wondering, is this an immune disorder or is it classified as something else. Does anyone have any info about it? I know a little bit about it, but not as much as I'd like to. B/f breaks out when in the sun & he's doing a lot better with his new meds. (which I only know is impossible to spell & pronounce according to him) I want to know more so I can understand what he's gone through/is going through & so I could maybe help in some way. I want to be supportive. Any info would be greatly appreciated.
