Red, C-shaped Rash Under The Arm On Upper Ribs, Not Spreading To Other Body Parts. What Could It Be?

I have a red c-shaped rash under my arm on my upper ribs. It s radius is about an inch and a half. It has been there about three weeks and has not spread to anyone else in my home, including my girlfriend who sleeps in the same bed. It also has not spread to other parts of my body. This lack of contagious qualities makes me think it can t be ringworm , but what else could it be?
