I've had a small red spot on my bicep for approx 2+ weeks. It started as a dry red oval spot about 1/3 inch or 8 mm. It wasn't itchy or painful. Two days ago, I cleaned the spot with alcohol and put on some antibacterial cream and covered it with a band aid. The center of the spot has returned to my normal skin color but the circumference has not, leaving a red ring, slightly bumpy. It hasn't grown larger but I'm worried. Should I continue the antibacterial cream? Is it time to see the doc?



I don't know if it is a bug bite/sting since I don't see any bite marks, holes, etc. I don't know if its ringworm since it is now a red ring but I haven't read any instances of the red ring forming as a red spot first.
