So my dd is 13 and she hurt her finger in pe today and after running it under cold water for 20 mins at school and putting ice and arnica on it at home and resting it shes still complaining its hurting even more now and the swelling hasnt gone down, she cannot use her whole hand because its too painful, shes had 2 paracetamols which dont usually work for her but shes allergic to ibuprofen. what should I do now as I seem to have done all I can
