My daughter was bit by something that started like a blister but now looks like a ringworm.

Seek medical care: Ringworm starts off as a small red dot that then fades. You will notice a circular/ oval like reddish ring made up of small individual reddish circles or bumps with normal skin color inside the ring. If it looks like that, you can either seek medical care or pick up some athletes foot cream or womens vaginal yeast tx cream (act ingred ends in -azole) and apply to the lesion 3 times a day.
