One dermatologist said he thought light therapy would help with the itching, but then said it would affect my lupus, which is not active, have issues. He also said he thought living in a hot climate would help the itching, but lived in Tucson for several years and still had severe itching. I can't believe all those drs, could not figure out the itching. I now have some itching on scalp but shampoo with tea tree oil really helps. So thankful with this site and my diagnosis.
