My 6 year old son started getting this rash around his left eye. We took him to his pediatrician and advised us to use elidel cream. After 2 weeks, it was not showing any signs of going away. Last week my wife took him back in. This time she wanted us to try an antifungal cream. We started using that. My wife just sent me a pic and it has grown rapidly! Any suggestions on what this could be?
