Often, Lupus patients develop hives which can cause itchy skin. Are the areas red weals? Also, lupus rashes can itch when your disease is active.
Also, some medications can have itchy skin as a side effect, especially medications used for Lupus Nephritis; medications used for symptoms of Fibromyalgia; medications used for migraines; medications used for Raynaud's Syndrome; and medications used for Restless Leg Syndrome ( A neurological disorder where legs develop and crawling, aching skin sensation which is relived by moving the legs).
There are a number of things that could be causing this itch. Discuss this with your doctor to see if you can narrow down the cause and find a treatment that works.
Peace and Blessings
Look For The Good and Praise It!
