Good evening. My mother aged 60 is a diabetic patient on insulin and also a kidney patient. It's been a week she's having severe itching and gets worse during night. She's taking blood thinner and bp medicines during the night. There is no redness. Her LFT was done last year which was normal but her creatinine and blood urea was high, 2.0 and 61 respectively. Skin remains dry almost whole of the day.
