hi! and welcome,
I am so SO glad you are terminating your lease. Please don't delay, and maybe your state health dept. could help you move sooner. Do NOT let the landlord drag her feet at ALL!!
I don't think lupus has any identified cause, but environmental triggers can certainly cause a flare up of underlying illness. And, as so many of us know, autoimmune illness can evidence itself in any kind of symptom it wants to. When I found this site I read lots of old threads, and learned so much.
Take care and keep us posted,
hugs,
suetoo
