I have a somewhat semi-circle set of bumps on my left arm. They appear to be three or four of them. Slightly more red than my skin color and slightly raised. I also have two other smaller bumps, somewhat similar, closer to my elbow on the back side of my forarm. I would have posted a picture but my digital camera could not take a decent photo. I have no insurance and can't afford to go to a dermatologist. They do not itch and they haven't gotten any worse or better, that I can tell. If someone could tell me, possably, what they are and how to treat it would be much appreciated!
