I would think that menopause and/or perimenopause could cause similar symptoms as lupus. My mother had lupus, and her doctors were constantly trying to trigger early menopause with her because they said after menopause, lupus can go into a semi-permanent remission (so perhaps hormones have quite a bit to do with the cause of lupus). They were not successful in inducing menopause in my mom, but it was certainly worth a shot. Maybe you can ask your doctor about that.
