Lupus is a disease that occurs when your body's immune system attacks your own tissues and organs (autoimmune disease).
Inflammation caused by lupus can affect many different body systems including your joints, skin, kidneys, blood cells, brain, heart and lungs.
One common early symptom that can be indicative of lupus is a photosensitive rash, meaning a rash that develops in response to sun exposure, particularly on the face and upper arms.
Other early symptoms of Lupus are unexplained fever and pain, swelling, and stiffness of multiple joints.
