About a month ago I noticed a small red bump that resembled a pimple or possibly an ingrown hair on the side of my stomach near the bottom of my rib cage...so I squeezed it, but it wouldn't pop. It doesn't itch, but it's getting bigger (about the diameter of a pencil eraser now), and three more little bumps have appeared in an area about the size of a silver dollar around the first. The new ones are all really small, and the first bump appears to be developing a little white crater in the middle. Again, these aren't painful or itchy, and they don't seem highly contagious, but I am concerned because they aren't going away, and they do seem to be slowly spreading. I would go to the doctor, but I was recently laid off and lost my insurance too. I am including a photo of the area.
