It sounds like a migraine attack to me , with the eye problem and the vomiting. I think a visit to the doctor would be best and he will have some meds to help her .
she didn't hit her head. she said her vision is blurry unless she really focus on an object. she vomitted yesterday evening, then again this morning before we rushed her to the children's hospital, and then she vomitted again two hours ago.
Has she hit her head recently ..how is her eyesight is she seeing okay ?
