Hi. Is the affected area warmer or hot to the touch ...as compared to unaffected areas? Try mixing 50% Hydrogen peroxide w/50% water.Pour it over the affected area..and repeatevry 4 hours... until it looks like it's getting better. If it get worse..and there is a foul smell present..go see your primary care Doctor as soon as you can.

Hope this helps ya'!
