I am not a qualified medical professional, but that looks somewhat like mine, and leaving the band-aid off for a day helped immeasurably. (Obviously, only when I was doing clean, dry activities - I put a band-aid and a rubber glove on when I made some jam.) The jagged edges got all disgustingly dry and eventually flaked off

If it makes you feel better, maybe stop by the campus quick clinic and have the triage nurse look at it? That's the person who told me I'd be fine if I stopped keeping it so wet and squeezing it with a band-aid. And he was right, in my case.
