My son is 5 years old and he has had an on again/off again rash around his mouth. It seemed to start from chapped lips and he keeps licking and biting his mouth because it itches. When this flares up it sometimes gets on the sides of his mouth also. The rash is red, no bumps or lesions. I am concerned that this will scar, it hasn't completely gone away for a few months.
Any ideas?
