How Long Do the Symptoms of a Lupus Flare Usually Last?

Lupus flares are unpredictable, and there is no way of knowing how long they may last, according to WebMD. Symptoms of a lupus flare may include profound fatigue, low-grade fever and pain in the joints and muscles.

Other symptoms of a lupus flare include skin rashes, extreme sensitivity to sunlight, weight loss and mental confusion. Some cases of lupus come with complications such as kidney and heart problems. Most people with lupus can continue their normal daily activities, says WebMD. Treatment for lupus depends on the severity of the symptoms. For mild cases this involves the prevention and control of symptoms. In more severe cases where organ damage may occur, doctors may prescribe corticosteroids or immunosuppressants.
