The course of lupus varies by individual and is hard to predict, because symptoms come and go. Lupus usually develops so slowly that a person may not notice the symptoms for a long time. Sometimes lupus develops and progresses rapidly.
Periods of time when you have lupus symptoms are called FLARES or RELAPSES. Periods of time when your symptoms are under control are called REMISSIONS. Flares and remissions can occur abruptly, unexpectedly, and without clear cause. There is no way to predict when a flare will happen, how bad it will be, or how long it will last. When you have a lupus flare, you may have new symptoms in addition to those you have had in the past.
