Hello. Do you take any tests of diagnosing kidney disease? How much is your creatinine and GFR? Generally speaking, high creatine and low GFR will result in itch. If you have no idea about the underlying reason of itch, you should take a kidney function test in hospital to figure it out. If it’s kidney disease, you can try to use Funeng Therapy that is quite professional in the field of kidney disease.
Could it be related to a possible food allergy? Just a thought.
