Yes, I would like to know what doe diabetic sores look like? I am a diabetic and I have these dark itchy bumps on my arms, there is 4 in a row on my left and one on my right wrist and 2 on the back side of my arm they have been here for a long time, they itch really bad when I scratch them they get raised. I have been to several dermatologist they give me medication that will work in the beginning but stops, the bumps seems to be going away, but they come right back. Can someone help me please, I m so uncomfortable.
