Question: Red spot on arm

 guest2009 - Tue Nov 17, 2009 5:01 pm

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.

User avatar Hello,Fungal infections typically grow at the periphery with a central clearence thus growing in size.Antibacterial cremes would not help here but antifungal cremes.Of course there are other conditions like a drug rash,which can presnt with a dull red center and a pale periphery known as target lesions.Your history does not support this.Granuloma annulare is one other condition which could present like this.If this persists do get examined.Best wishes.
