Gi upset: You have some sort of of GI upset. The mild fever that is now gone, points toward a mild viral illness. These are usually self limiting, meaning that with clear liquids and rest for a day or two, and then slowly increasing your diet to a BRAT (Bananas/rice/applesauce/toast) diet (soft foods and increasing as tolerable) you should feel better. If no relief, than see the dr. for other causes. Goo
