Hi, Laura. Later I found something along the lines of what you describe, but I didn't recognize the authors of the findings & thought that the article was possibly a sales pitch...? (Not sure...) The rheumie/authors I listed are considered mainstream and are "big names" in the field, for what that's worth.
FYI, Plaquenil can take upwards of 4 months to reach its full effect.
Your rheumie sounds very together, by the way. I'm smiling over that, because I meandered from dr. to dr. while covered with bizarro rashes, and STILL none of the suburban dermies or rheumies (etc.!) I saw recognized an SCLE annular-type rash, so none believed I had any form of lupus, even after multiple telling skin biopsies. You may have hit the rheumie jackpot?
Anyway, take good care. Sincerely, Vee
