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.
But most people can control their symptoms and prevent severe damage to their organs. They do this by seeing their doctors often for checkups, getting enough rest and exercise, and taking medicines. This topic focuses on systemic lupus erythematosus (SLE), the most common and most serious type of lupus. But there are other types of lupus, such as discoid or cutaneous lupus, drug-induced systemic lupus, and neonatal lupus.
