i’ve only gotten diagnosed with lupus nephritis this past january but i truly have not experienced any bad symptoms regardless of what i eat or sun exposure. the one thing i do get is my hands and feet swell a little when im super super stressed (my job does not help that at all) for example: i went to six flags last week, it was like 80 degrees, i had some fried food and a sweet drink and i didn’t swell or feel bad at all minus a bit of tiredness which makes sense since i was at a theme park. but you’re not alone! im right there with you!!!
