I also had severe itchy skin on my hands to begin with. Went to alergist, did patch testing, I am allergic to tixocortal pivilate. Sure nobody knows what that is but I stopped using all kinds of soaps, detergents etc. I had an ointment prescribed that helped. Itching went down to the backs of my knees, my neck and a few other breakout areas. Oinment helped but when I passed a 7mm kidney stone most of the itching and skin irritation is gone. Have an appt with urologist in 2 weeks and allergist in a month. I am convinced itching is from kidney. Doctors give me a HMMMMM. Never been diagnosed with CKD or other issues but I will continue to explore.
