Hi Sami!
Welcome to the Board, we’re glad to have you. Itching is a common (but not much fun) side effect when your kidneys are failing. It can be caused by a few different things:
– Overall dry skin as the fluid balance in your body changes (try ultra-moisturizing lotions and re-apply often)
– Buildup of wastes in your bloodstream that your kidneys are not removing (Do you know exactly what your kidney function is? It may have dropped a bit more. IF your doctor advises it, drinking lots of water may help flush out wastes. If your doctor is suggesting that you LIMIT fluids, follow his or her advice–he or she knows you best.
– Buildup of phosphorus in your bloodstream that your kidneys are not removing. If your doctor has not prescribed “phosphate binders” for you to take with each meal and snack, ask if these are something you need. Common phosphate binders include OsCal or Renagel, but there are others
Other folks may have more ideas for you, too.
