Hello, I Came Down Sick Just Under A Week Ago.

Hello, I came down sick just under a week ago. I carried a fever along with muscle cramping, vomited 4-6 times. I do still have diahrrea but my biggest concern is a horrible stomach ache (cramping). I am not dehydrated and I am starting to eat small amounts again. I do not feel that I need to go to the ER. I am in Ohio. Any ideas on the type and what I can do for the stomach ache or how much longer I can expect it?
