Aches:
as so much of the disease is still unknown, so is the life span of one with lupus. If you have mild involvement, you can most likely live a fairly normal life.
Anytime that you add more or different organ involvement (kidneys, liver, heart, cns), there is just no way to know. You can be fine one day and critical the next (as some of us have experienced).
I hope this finds you well,
