Well, we thought Trent had a cold sore. After almost 2 weeks of being on a anti-viral, he had 3 new spots & more on the way. Man did they look painful. We took him back and got the correct diagnosis of impetigo. He is now on an anti-biotic. Impetigo is kind of like a strep/staph infection of the skin. It oozes, leaks, cracks and bleeds, down right nasty.
