I'm a mommy of 4 and it sounds to me like it may be this common virus called "hand, foot, mouth". If this is what she has you just have to look closely at her hands, feet and the inside of her mouth you may actually see other little red dots or small blisters. It's very contagious but it isn't dangerous. In fact my kids have had some very mild cases of it. The doctor just recommends lots of fluids and tylenol for any pain or discomfort. Good luck!
