Suggest Treatment For Fever Followed By Ear Pain, Throat Pain And Vomiting

My 24 year old daughter who lives 3 hours away promises she only has a cold and a good night s sleep will take care of everything. I however, doubt it. Last night she said one ear hurt and the same some of her throat hurt. About an hour ago she said her stomach was upset and thought perheps that was due to drainage. 30 minutes ago she texted and said she has thrown up three times. She claims she doesn t have fever
