Dysfunction in the sacroiliac joint, also called the SI joint, can sometimes cause lower back and/or leg pain. Leg pain from sacroiliac joint dysfunction can be particularly difficult to differentiate from radiating leg pain caused by a lumbar disc herniation (sciatica) as they can feel quite similar.
Systemic lupus erythematosus (SLE), also known simply as lupus, is an autoimmune disease in which the bodyâs immune system mistakenly attacks healthy tissue in many parts of the body. Symptoms vary between people and may be mild to severe.
Systemic lupus erythematosus (SLE) is the form of lupus that can harm your skin, joints, kidneys and brain and may be fatal. The other form of lupus is called discoid lupus erythematosus, which affects only your skin. Systemic lupus erythematosus (SLE) that affects the kidneys is called lupus nephritis. Lupus is an autoimmune disease, meaning your immune system (your bodyâs defense system), which usually protects the body from disease, turns against the body. This causes harm to organs and tissues, like your kidneys.
