I have itchy bumps on 1 elbow, they itch, no oozing, then they peel. It started on my pointer finger about a year ago, but went away. About a month ago, a bump appeared on a different knuckle, itched, then peeled. Now my left elbow has several very itchy, dry, peeling bumps. Can this be scabies? The only place the bumps are is on my elbow.
