Hi, I’m new here, and have CKD with Lupus. I had the horrible itching problem head to toe for over a year. It drove me nearly insane and I have scars from scratching. After being hospitalized and getting my potassium and phosphorus levels under control, the itching is almost gone! I believe I have read that extreme itching can be a side effect of the high blood phosophorus levels. I take a phosphate binder for now and avoid all dairy and foods with high phosphates. Hope you get some relief soon.
