Help don't know what this is

Marie • Hello, my name is Marie, I'm 27 years old and I joined this website the moment I found out that I was pregnant. This is my first pregnancy and I'm praying for a 100% healthy baby boy or girl 😊

My son is 3 and has had this on his leg since April/may. The Dr.s just gave me baccintrate and one gave me some cream but it's not working
