Urgent Care. Two of our kids have had this weird sickness where they get a high fever of 103, and say their stomach hurts but haven’t thrown up and feel well enough to eat if on fever relievers. My daughter is on day 4 of the fever and said her throat was hurting so my wife took her in to get tested for strep. It came back negative, the doctor said the symptoms don’t sound like anything for the other tests they do, so she just prescribed an antibiotic just in case and sent us on our way.
