Any flare can be lethal.

The secret to controlling lupus in a healthy way is to be very aware to the beginning of an attack and to the things that provoke them.  It is, for me, of vital importance to stop an attack at the very beginning, for once started it grows ever larger, like a snowball rolling down the mountain.  We have to remember that even if it’s the beginning of a flare, if it attaks a vital organ it has the potential to kill us in a few days.  As we never know what our immune system will decide to destroy, we can never take it for granted. So the best course is to keep the flares at bay, acting decisively from the very beginning to stop them.  So, be very aware of your body, monitor yourself every day.  Anything, even if it seems insignificant, can be an alarm signal, do not ignore any symptom or change.
