Redness around cut
My father suffered a cut on his left leg during his morning walk. He doesn't know how and when he got cut. This happened 8 days ago. Now there is redness around the area and he says it's very itchy. It also pains occasionally. Please suggest what this is exactly and what shall I do to resolve this problem. He is 54 yr old, diabetic and had a CABG done last year. Thanks.
