Hi. My Daughter Has Woken The Past Four Mornings With

Hi. My daughter has woken the past four mornings with a very swollen face. Her eyes and right across the bridge of her nose. She said her jaw aches and also feels like her throat is swollen. She is 13 and has regular periods. My regular GP was away when I took her on Friday and the Dr we saw said it must be an allergy and gave her anti histamine. So far they have not helped at all. Should we seek further advice?
