I have a raised area, like a pimple, on the back of my arm near the elbow. The area is warm to the touch plus has an obvious outer ring about 4 inches from the raised area. This outer area is approximately the size of a baseball in diameter. I tend to have frequent cellulitis infections in my legs due to poor circulation (last bout was in March and I ended up with an abcess opening up on my leg that is close to being healed).
