Lord heal this daughter from that itching and dryness if her foot. I suffered also when I was a child from a fungus like that, and they finally realized it was the sneakers. I was allergic to whatever material they used to make them. Creams and oils made me worse, washing the foot airing it and keeping it clean will help. A doctor can be able to treat her with the best remedy for her. Lead them to the right medication for this child Lord for I know how painful it can be. I pray in the mighty and merciful name of Jesus Christ, amen.
