In night majorly I got itchiness in legs from below the abdomen to ankle of leg from last 4 to 5 months for that blood test I have done. I got liver function test all are ok but in kidney blood test blood urea nitrogen came 5.93 mg/dl (normal range 7 to 18 mg/dl) and creatinine 0.61 mg/dl (normal range is 0.7 to 1.4 mg/dl). Bothe my urea nitrogen and creating came less so whether my skin itching is due to kidney problem or not.
