My mother is a diabetic. We always keep a check of her blood sugar level. Yesterday it was 170 and today it is 260. It keeps fluctuating and the max it has gone far as 400. She is taking her sugar medicine. She is not on insulin. She has this issue where her leg starts to feel itchy and the itching is so intense that she scratches it till her skin comes out. Her legs also feel numb. We have shown it to numerous doctors  but no one has given us a solution for that. I don't know it's because of diabetis or a skin infection. We have even shown it to the dermatologist and to diabetis specialist but no results yet. Can anyone help us with this situation.
