I have a 16 yr old male son who was to hospital Sunday due to fever x 3 days, sore throat, dizziness and vomiting. He was treated with IV fluids, IV Gravol and Dexamethasone for his throat. He was then sent home with antibiotics for throat. He has continued to sleep since Thurs, drinking fluids, eating very little and today has complaints of headache, light sensitivity/strained eyes and dizziness/light headedness. He also has began having diarrhea. Would this require a return to hospital or might this be a flu, he has been sick since Thursday and does not seem to be getting any better
