We agreed to apply the antibiotic cream, Mupiricin, because we were worried about any serious infection, but we were against the corticosteroid for all the side effects. Thank goodness, he was open minded and said that we could replace it with something natural like coconut oil.
So, we applied the antibiotic cream in the affected areas with a homemade infusion (shea butter, coconut oil, primrose oil, neem oil, manuka honey) and she responded very well.
We are now waiting for the results of her IGG test to know her food intolerances.
